How to eat well in London without being ripped off

Most guides hand you twenty restaurant names. Half will have closed, changed chef or gone downhill within eighteen months, and you'll be standing outside one of them at 8pm reading a menu that no longer matches.

So this isn't a list. It's the set of rules that reliably separates a good meal in London from an expensive bad one — and a handful of institutions solid enough to name.

The six tells of a place to avoid

A picture menu. Photographs of the food on a board outside. Almost universally a bad sign in London, though not in every country.

Someone standing outside inviting you in. Restaurants that are any good in London do not need to solicit from the pavement. This is close to a perfect negative indicator.

A menu that does everything. Pizza, curry, fish and chips, burgers, pasta, all on one laminated sheet. Nobody cooks six cuisines well.

It's within sight of a major landmark. Leicester Square, the immediate streets around Piccadilly Circus, the parade opposite the Tower, the strip by Westminster Bridge. Rent is extreme, the customer is never coming back, and the food reflects both.

Union Jack bunting and "traditional British" signage. Real London pubs don't advertise their Britishness. They just are.

No prices displayed outside. Legally they should be. Its absence tells you what they expect you to think when you see them.

Where to eat instead

Markets, at lunch. Borough Market is the famous one and it deserves the fame, though go on a weekday if you can — Saturday is more crowd than market. Maltby Street and Brick Lane's Sunday markets are less overwhelmed. You'll eat well for £10–15 standing up.

Pubs, but the right ones. A pub that is busy at 1pm on a weekday with people who look like they work nearby is serving decent food at fair prices. A pub that is empty except for tourists is not. Sunday roast in a good London pub is one of the best-value meals in the city, usually £18–24.

The cheap-eats capitals. Chinatown for Cantonese and Sichuan, Brick Lane and Whitechapel for Bangladeshi, Southall or Tooting for South Indian if you're going further out, Green Lanes for Turkish. These are neighbourhoods where the food is aimed at people from that community, which is the only reliable quality signal there is.

Bakeries and sandwich shops at lunch. London does an extremely good £6–9 lunch. Sitting down for lunch every day is what wrecks a food budget.

The institutions worth the detour

A handful of places have been consistently good for long enough to name without much risk:

• Borough Market — for grazing rather than a sit-down meal
• Brick Lane's 24-hour bagel shops — salt beef, a few pounds, open at 4am
• St John, Smithfield — the restaurant that reset modern British cooking; not cheap, worth it once
• Any branch of a good chain you've never heard of — London's mid-market chains are unusually strong, and a "chain" here often means five sites run by the people who started it

Book anything popular. London restaurants take reservations weeks out, and the good small ones have thirty covers.

The money rules nobody explains

Service charge is usually already on the bill. Typically 12.5%, added automatically, described as "discretionary". It is genuinely discretionary — you can ask for it to be removed, and asking is normal and unremarkable. There is no expectation of a further tip on top.

Tipping culture here is mild. If service isn't included, 10% is generous and nothing is acceptable in a pub. Nobody chases you down the street.

Tap water is free and always available. Ask for tap water specifically, or you'll be brought bottled at £4.

Cover charges are rare and a bad sign. A per-person charge just for sitting down is not a normal London practice.

Check the bill for the double-charge. The classic tourist-strip trick is service added automatically and a blank tip line on the card machine. Look before you tap.

Three things that make food cost less

Eat your big meal at lunch. Set lunch menus at genuinely good restaurants are often half the evening price for the same kitchen. Two courses for £20 at lunch, £45 at dinner, is a normal London spread.

Pre-theatre menus. Around the West End, 5pm–6.30pm, two or three courses at a steep discount because they want the table twice. You don't need a theatre ticket to order one.

Supermarket meal deals. A sandwich, snack and drink for around £4–5 from Boots, Tesco or Sainsbury's. Not glamorous, but a park bench in St James's with a decent sandwich beats a bad £20 lunch by a distance.

The one thing to spend on

Have one properly good meal. London is one of the best restaurant cities in the world, and eating exclusively from markets and meal deals means missing the thing it's actually great at. Book somewhere real, go at lunch to halve the price, and treat it as an attraction rather than a meal — because at that level, it is one.
