Cocktail Bars We Trust The best cocktail bars London runs, and where to drink in London by register — from a grand-hotel martini to a Bethnal Green classic

"I drink for a living, and these are the bars I keep going back to" is Nathaniel's standing line about this list, and it holds. No trend bars chasing a TikTok garnish — just the rooms that get the drink right, from the best martini bars London runs to a daily-changing menu in Bethnal Green.

How this list of the best cocktail bars London gets made

Every bar here has been visited on a normal Tuesday, not a press night, and the drink ordered was always the bar's own signature or house classic — never something built to photograph well. The best cocktail bars London can claim earn the spot on an ordinary night; a room stays on this list only for as long as that consistency holds, and two of the entries below are recent enough that they're still being watched.

Where to drink in London: grand-hotel bars vs. neighbourhood bars

London's better cocktail bars split roughly into two registers, and where to drink in London depends on which register the night calls for. The grand-hotel bars — The Connaught Bar, which anchors the cocktail bars in Mayfair, and Dukes Bar — do a specific kind of theatre well: trolley-side service, a signature drink built and finished at the table, staff who've been doing this for decades.

The neighbourhood bars — Satan's Whiskers, Seed Library, and increasingly Cato — trade that ceremony for a looser, more experimental room. This register also absorbed the speakeasy bars London spent a decade opening: basement rooms like Seed Library keep the hidden-door feel without the password theatre. Neither register is objectively better — the best cocktail bars London holds sit in both.

What's new on this list

Seed Library, tucked in the basement of One Hundred Shoreditch, earned its place among the best cocktail bars London has on genuine ingredient curiosity rather than a famous name alone — the Purple Shiso Martini is the drink to order on a first visit.

Cato is the newest and most ambitious addition, a five-storey Seven Dials opening that splits into an upstairs julep bar with mint grown on-site and a downstairs seven-colour cocktail menu — genuinely two different nights out under one roof, and both halves already among the best bars in London for what they set out to do.

Booking the best bars in London

The best bars in London split three ways on reservations. The cocktail bars in Mayfair and St James's are the ones worth planning ahead for, particularly for a trolley-side or window seat — a few days' notice is sensible for a weekend. Satan's Whiskers runs no-reservations by design, which is part of its appeal; turn up and expect a short wait rather than trying to book around it. The rest sit in between: fine to walk into on a quiet weeknight, worth a booking for a group of four or more on a Friday.

Where the night runs on after last orders is a separate question, and near Marble Arch the answer is not a bar at all. Grosvenor Casino The Victoria on Edgware Road keeps a second-floor dining room serving from 6pm — grills with a Middle Eastern accent, rebuilt in a £15 million refurbishment — inside a venue whose gaming floor never closes.

Dress and atmosphere

None of these rooms enforce a hard dress code, but the best martini bars London offers — Dukes and The Connaught above all — skew smarter in practice: most guests dress as they would for a nice dinner rather than a casual night out. The neighbourhood rooms and the speakeasy bars London still runs are casual by design, and turning up overdressed at Seed Library or Satan's Whiskers will feel more conspicuous than turning up underdressed at The Connaught. In the end, where to drink in London on a given night is a register question, not a list question — pick the mood first and the bar follows.
