Finding Us

The address:

Metal Box Factory
Suite 441, 4th floor
30 Great Guildford Street


If you're travelling with a Mozilla group, e.g. for work weeks, you will more than likely be staying in St. Martins Lane Hotel. We’re the glass fronted building directly opposite that hotel.

If you’re travelling by Tube (London Underground) the closest station to the space is Leicester Square (0.1 miles, 2 mins) which is on the Piccadilly line.

From Leicester Square underground station

  1. Leave the underground station by exit 1 (Signs to Charing Cross/St Martins Lane)
  2. First left (Sharp; down alley)
  3. Right (@dead end),
  4. Left (@ J Sheekey)
  5. Right (onto St Martins Lane)
  6. Building 101 is soon after Starbucks, but before The Duke of York's theatre.

Video of the route, route on Google Maps

From Charing Cross underground station

  1. When exiting Charing Cross, cross over the traffic lights and on towards Trafalgar Square
  2. Before crossing the road directly in front of Trafalgar Square take a Right and head towards St. Martins Lane
  3. You'll find us after the Duke of York Theatre; if you see Starbucks you’ve gone too far

Route on Google Maps

Travelling to London

If you’re coming from continental Europe, you may wish to explore the possibility of using either the Eurostar train, or choosing a flight that will arrive at the London City Airport, as both of these options will drop you conveniently close to the centre of London.

Trans-continental travellers should expect to arrive at either Heathrow or Gatwick airports. While these airports are quite distant from the city centre, both are relatively well serviced by above and underground trains, as well as bus and taxi service.

From Heathrow by train

  1. Take the London Underground (“the tube”) from the Heathrow terminals towards the city centre (Heathrow is at the end of the line). Heathrow has three London Underground stations – one for Terminals 1, 2 and 3; and one each at Terminal 4 and Terminal 5. Heathrow Terminals 1, 2, 3 station is in the central area between the terminals, which are a few minutes walk away via underground walkways. Terminal 4 and Terminal 5 stations are in the basements of the terminal buildings. More details.
  2. Get off at Leicester Square, but please note that this station is not wheelchair accessible
  3. Follow the Leicester Square tube walking instructions found under Finding Us

Travelling to London on the Piccadilly Line takes around 50 minutes. It has no connections, costs £5.30 cash, or £2.90 Oyster card each way. Beware that staff will be encouraging people to buy Heathrow Express tickets, but these are not what you want for the Underground and will take you to Paddington on the other side of town. Buying a top-up Oyster card is highly recommended as these reduce fares by up to 50% and can be refunded (including deposit) at the end of the trip.

From Heathrow by car

This company offers fair priced car transport (much cheaper than hailing a cab from outside the airport): Heathrow Cars

From Gatwick by train

  1. Head to the railway station outside the South Terminal (is only a few minutes away from the North Terminal by a free shuttle)
  2. Take the train to London Bridge, they come regularly (avoid Gatwick express)
  3. At London Bridge change to the Northern Line on the Underground
  4. Get off at Leicester Square
  5. Follow Leicester Square tube walking instructions under Finding Us

Travelling around in London

If you are spending the day in London or plan on moving on from us at any time here are some useful travel links to help you on your way:

The Great British Summer

The UK has a bit of a reputation for poor and unreliable weather but don't let this stop you from coming down. Just take a look at BBC Weather or Met Office weather and see if you need an umbrella or sun screen.

Smoking Policy

Pursuant to both the Health Act 2006 (c 28), and the tenant agreement of 101 St. Martin's Lane, smoking is not permitted anywhere on the building premises — this includes the common areas as well as balconies and other attached outdoor spaces. If you want to smoke head on out to St Martins Lane and over to near the Duke of York. This is where our no-smoking area ends.

Dog Policy

Dogs are allowed on the Mozilla floors but not in the rest of the building. Therefore bringing in your dog will require you to carry the dog through reception area and up through the fire escapes. You need to make sure someone is at the office end to let you in. See the full Mozilla London Dog Policy for more information on accepted behaviour and rules.

Our meeting room names — a history of British television comedy

Dad's Army

A sitcom set in World War II, a bumbling and mostly incompetent division of the Home Guard usually ends up blowing up an innocent farmer's tractor while trying to defend Britain from the Nazis.

Fawlty Towers

A tired and frustrated Hotel owner/manager, played by John Cleese, treats all of his clients with thinly veiled contempt.

Red Dwarf

Three million years after a disaster that wipes out the crew of Jupiter Mining Corporation's Red Dwarf, the ship's computer releases Dave Lister from stasis. He is the last human being. For company he has a hologram of his dead bunkmate, a fashion obsessed lifeform that has evolved from his cat, the ship's deranged computer, and a self-deprecating service mechanoid.

Yes Minister

This sitcom is based around the battles betwee a Government minister and his Civil Service staff member who seemingly tries to scupper every attempt to pass legislation.

Food and Drink

London has a full range of culinary experiences ranging from some of the best restaurants in the world through to terrible tourist traps. This is an incomplete guide to some of the eateries in the vicinity of the office. If you have a particularly good — or bad — experience elsewhere, please add it to the wiki to help future Mozillians.

Coffee and Cafes

  • Monmouth Coffee (reviews): Providers of the office coffee beans. They have excellent espresso and pours. Tiny, quite busy, has communal tables in the back. Some seating outside–nice in summer!
  • New Row Coffee: Small coffee shop close to the space. They are a funny bunch of opinionated coffee lovers, and won't serve you an espresso in a take away cup because that's just not how espresso is meant to be had. Good alternative to Monmouth if you don't feel like walking there or if Sunday (because Monmouth doesn't open on Sundays). They also have yummy sweets and pastries, and loyalty card scheme, with plenty of hearts <3.
    • Note: About a minute's walk down St Martin's Lane, this is the closest good coffee shop to the space. Be warned – you aren't going to get a bucket of coffee, like you may from Starbucks – but it's going to be well worth it. If you plan on visiting a few times, or there are a bunch of you then it may be worth getting a loyalty card – one free coffee for every eight stamps.

A note on notes: the staff seemed quite disinterested to do any actual work the last time I visited, so that was the last time I visited.

  • Bageriet: Authentic Swedish bakery in the heart of London. The ideal place to get your fix of Kanelebulle, Vaniljhjärtan, and all manner of other Nordic treats. (24 Rose St)
  • Timber Yard: If you enjoy hanging out with MacBook-toting hipsters this is the place to be. Fortunately they also do great tea, coffee, and sandwiches.
  • La Gelatiera: Award winning ice cream, just around the corner from the space. Although some of their flavours are off the beaten track, the results are invariably delicious. More traditional varieties — such as the amazing chocolate sorbet — are also top notch. Highly recommended. (27 New Row)

Bars and Pubs

Close to the space

  • The Harp: Quaint little bar usually overflowing with local workers having a pint after work. Very convenient to the space. (Covent Garden, 47 Chandos Place)
  • The Bedford & Strand: Just a couple of blocks from the space is this fairly unpretentious wine bar which is often not too busy either. Great selection of European wine and cheese and meat plates to go with or a meal if you please. (1A Bedford St, 3 minute walk)
  • Ship and Shovel: This tiny pub spans two side of an alleyway and I once saw Kristin Scott Thomas there. (1-3 Craven Passage, 5 minute walk)
  • Experimental Cocktail Club (speakeasy): This is a cool and often busy speakeasy in the heart of China Town. Cocktails are excellent but pricey £10-12. (13A Gerrard St, Chinatown)
  • Waxy O'Connors
  • The Breakfast Club (speakeasy): Enter the fake SMEG fridge in this All Day Breakfast restaurant to find the speakeasy bar named Mayer of Scardy Cat town. Average Cocktail Price £6-8. (33 D'Arblay St)
  • Purl (speakeasy): A 20s speakeasy in the heart of Marylebone. Average Cocktail Price £7-9. (50/54 Blandford St)
  • Royal George Pub: A pub near Tottenham Court Road tube station. Make sure you go there on a Wednesday. All the local Ukulele players show up for some impromptu song playing. (133 Charing Cross Rd)

Further from the space but of interest

  • Princess Louise: This pub’s interior has been restored to its Victorian era state and is possibly one of the prettiest pubs you’ll visit in London. (208 High Holborn, 15 minute walk)
  • Ye Olde Cheshire Cheese: This maze of underground rooms serving as a pub was rebuilt after the great fire of 1666 and was believed to have existed since 1538. History: Britain has it. (145 Fleet Street, 25 minute walk)
  • Graphic Bar: This bar in Soho stocks 180 types of Gin and serves their gin mixes in paint tins…! (4 Golden Sq, 15 minute walk)
  • Fernandez and Wells: Small wine bar, suitable for groups of two or fewer. (Lexington St, 20 minute walk)
  • Jub Jub @ Callooh Callay (speakeasy): Speakeasy loosely based on Alice in Wonderland. Average cocktail price £8-10. (65 Rivington St, Shoreditch)

Chain restaurants

Unfortunately London is rife with mostly average tourist-trap chain restaurants which is a shame because with a bit of local knowledge you can find far better food elsewhere.

However there are a few “safe” chain restaurants that offer medium range food for medium range price if you’re happy with such compromises. The other benefit of these are that they can often accept large groups at short notice. If you really have to, our recommendations for these are:

  • Pizza Express: Ubiquitous chain favoured by middle class families, offering a reasonable selection of thin-crust pizza and pasta dishes.
  • Wagamama: Fusion Japanese. Not recommended if you are anywhere near china town.
  • Nando’s: I have nothing nice to say about this, so maybe someone else could try?
  • Jamie’s Italian: Reasonable chain Italian owned by the celebrity chef. Does a selection of pasta, meat and fish dishes but not pizza. Should always have some tables for walk ins (and booking isn't possible on a Friday evening or Saturday), but it's popular so you should be prepared to wait. (11 Upper St Martin's Ln, 2 minute walk)
  • Ping Pong. Dim Sum for when Chinatown is too much of a risk.

Stay away from: Steak & Co, Bella Italia, Angus Steakhouse, Prezzo, Spaghetti House, All Bar One, Masala Zone, TGI Fridays.


Why would you go to an average chain restaurant when the London space has Chinatown on its doorstep? London’s Chinatown is more Hong Kong-style due to British-Hong Kong historical relations so the food may be a bit different to your SF local. While not nearly as big as San Francisco’s it’s still a good place to get a meal. Try these few:

  • Plum Valley: More modern style Cantonese dim sum. (20 Gerrard Street, 8 minute walk)
  • Young Cheng: Dim sum and also famous for Lobster noodles. (22 Lisle Street, 5 minute walk)
  • Dumplings Legend: Dim sum, and fantastic Peking Duck. Prime-location in Chinatown, but very good. (15-16 Gerrard Street)
  • C&R Cafe: Reportedly-authentic Malaysian food at knockdown prices. The laksa is reportedly the best in the capital. (4-5 Rupert Court)


  • Koya: Japanese Udon noodles served in a deeply savoury broth. (49 Firth Street, 10 minute walk)
  • Abeno Too - Osaka-style Okonomiyaki: A Japanese omelette with your choice of fillings. (17-18 Great Newport Street, 4 minute walk)
  • Tokyo Diner: A top lunch choice for London Mozillians, this is a popular Japanese restaurant serving a large selection of unpretentious dishes at reasonable prices. (2 Newport Place)
  • Tobiko: Tiny Japanese takeaway offering either sushi or Donburi. (8 Garrick Street, 4 minute walk)


With the emergence of a fashion for street food, upmarket burger joints have been growing like a mold across London. Despite, or perhaps because of the wealth of choice, the subject of which are acceptable is a topic of much debate amongst London Mozillians.

  • Five Guys: American import and reportedly favoured by president Obama. However very few people leave to oval office for careers as food critics, and perhaps with good reason. There seems to be general agreement that the burgers are flavourless and the fries are over-salted. Also, for reasons best left unexplored the interior decor gives the impression that you are eating in a public urinal. (1-3 Long Acre)
  • Gourmet Burger Kitchen
  • Shake Shack: Famous from its NYC incarnation, but probably not worthwhile if one of the other options is available.
  • Byron: People disagree about the quality of the burgers, but the Oreo milkshake remains a popular choice.
  • Meat Market: Tucked away in the streets behind Covent Garden, this is an outpost of the London street food mini-empire that started with the “MEATwagon” burger van. Good selection of burgers, with the patties medium rare and juicy. The dead-hippie fries are practically a meal in their own right. (The Deck, Jubliee Market Hall, Tavistock Street)
  • Patty & Bun: Not near enough to the space for lunch, but if you are out and about a better burger than you will find anywhere in the Covent Garden area. Delicious, thick, medium-rare meat in a variety of inventive flavour combinations, sandwiched in a toasted brioche bun. (54 James Street)
  • Honest Burger: Thick, meaty, patty accompanied by ingredients that taste of actual food rather than the general mush of indistinct flavours that is all too common. All burgers are accompanied by excellent rosmary-salted fries. (4A Meard Street)


  • Mishkins: Jewish café/restaurant with a good line on cocktails, busy so small groups only.
  • Terroirs: Wine bar/restaurant offering small plates of French-style food, including charcuterie and cheese, for sharing.
  • Belgo: All things Belgian. Their specialities are Moules (for people not fans of seafood, there are plenty of other options) & a huge selection of beers & ales. Well priced, but often busy, be prepared to wait 30-60 mins on peak nights if you do not have a booking. Atmosphere is pretty unique - most seating is an underground cellar/cavern, serving staff are dressed as trappist monks &c. (50 Earlham Street, 7 minute walk)

Italian / Pizza

  • Polpo: "Venetian small plates"; authentic Italian food in sharing-size portions. Relatively inexpensive given the location and good food. May be worth visiting for the chocolate hazelnut cake alone.
  • Homeslice: Large (20") pizzas for sharing, or individual slices. (13 Neal's Yard)
  • Pizza Pilgrims: Artisan pizza with a sourdough base and Italian-style toppings. (11 Dean Street)
  • Pepe: Cheap boxes of pasta and pizza slices. (57 St Martin's Lane, 1 minute walk)

Spanish Tapas

  • Pix (16 Bateman Street, 10 minute walk)
  • Brindisa (46 Broadwick Street, 20 minute walk): Wonderful Spanish tapas.
  • Opera Tavern: Upmarket tapas restaurant serving a selection of Spanish and Italian influenced charcuterie and tapas dishes. Part of the Salt Yard group that seems to be well regarded by London foodies. (23 Catherine Street)

Fish & Chips

  • London Fish and Chips: MSC certified fish. (46 Bedford Street, 4 minute walk)
  • Rock and Sole Plaice (47 Endell St, 10 minute walk)


  • Bodean’s: American ribs, pulled pork, burgers and so forth to be eaten whilst watching American sport replays. (10 Poland Street)
  • Pitt Cue Co: The same American BBQ style but more expensive and more exclusive is the. (1 Newburgh Street, 25 minute walk)
  • Hawksmoor: Famous, upmarket, steak restaurant, offering ~1kg cuts for sharing. Hugely busy, so you’ll almost certainly need to book. The Air Street branch in particular has fantastic decor resembling a 1920s member's club. (11 Langley Street or 5A Air Street)

Indian / Pakastani / Bangladeshi

One of London's greatest culinary offerings is the wide selection of Indian restaurants. Of particular note:

  • Dishoom: Super authentic Bombay restaurant with great Indian food. Right down to only serving “local” soda pop. And only steps away from the space. (12 Upper St Martin's Lane)
  • Veeraswamy: Said to be the oldest surviving Indian restaurant in the UK. Now, one of the Capital's best with a Michelin star (make sure you're ready for the bill!). (Mezzanine Floor, Victory House, 99 Regent Street)
  • Red Fort: The best Indian restaurant in Soho, and previous winner of TimeOut's best Indian Restaurant. (77 Dean Street)
  • Area: Brick Lane: Synonymous with Indian cuisine in London. Not all restaurants here are worthy of the address however – those of particular note: Aladin (132 Brick Lane) and Cinnamon (134 Brick Lane). (134 Brick Lane)


Most restaurants will offer some vegetarian food, with some — such as Dishoom listed above — offering an excellent selection of meat-free choices. However there are also a few destinations that specialize in vegetarian food.

  • Mildred’s Vegetarian: A more upmarket sit-down restaurant. (Lexington Street, 15 minute walk)
