When I first heard the term “hidden bar” I imagined a speakeasy behind a laundromat. In reality, most of the spots I’ve visited are tucked behind ordinary storefronts, but they’re not invisible. They’re just a few steps away from the main street, with a door that looks like a regular shop front and a sign that reads “Open” in a hand‑written font.
What makes a bar truly hidden?
A hidden bar is defined by three concrete traits: a discreet entrance, a curated cocktail menu, and a relaxed vibe that feels like a private club. I’ve logged the following seven spots that tick all three boxes.
1. The Vault – 12‑hour opening, no sign
Located on a side street off Clerkenwell Road, the door is a plain wooden panel. Inside, a 12‑hour bar opens at 10 am and closes at 10 pm. The menu features a single signature gin cocktail, the “Vault Tonic,” priced at £12.50. The bar’s staff remember your name after the first visit, and the seating is a mix of leather armchairs and a communal table that seats eight.
2. The Back Room – 50‑seat, 24‑hour service
In the back of a bakery on Tottenham Court Road, a narrow doorway leads to a 50‑seat bar that stays open until 2 am. The cocktail list is limited to five classic drinks, each priced at £10. The bar’s lighting is low, with a single lamp on a wooden counter. The only drawback? The Wi‑Fi is weak, so you can’t stream music while you sip.
3. The Attic – Rooftop, 30‑seat, sunset view
Upstairs from a florist on Camden Market, the attic bar offers a 30‑seat terrace overlooking the city. It opens at 5 pm and closes at midnight. The specialty is a smoked whisky on the rocks, £14. The view is great, but the wind can be a nuisance on clear nights.
4. The Green Room – 20‑seat, eco‑friendly
Inside a converted greenhouse on Brixton Hill, the Green Room serves 20 patrons. All glassware is recycled, and the menu is plant‑based, with a signature cocktail made from cucumber and basil, £11. The bar’s only limitation is that it closes early, at 9 pm, to allow the plants to rest.
5. The Speakeasy – 10‑seat, 24‑hour, no menu
Hidden behind a laundromat on King’s Cross, the Speakeasy is a 10‑seat bar that operates round the clock. There’s no printed menu; you order by voice, and the bartender prepares a custom drink. The price for a standard cocktail is £13. The lack of a menu can be a hurdle for first‑time visitors who want to know what’s on offer.
6. The Underground – 15‑seat, themed nights
In a basement of a pub on Notting Hill, the Underground offers 15 seats and hosts themed nights every Friday. The menu changes nightly, but the “Midnight Mule” is a staple at £12. The bar’s only drawback is that the door is locked after 1 am, so you’ll need to leave early if you’re a night owl.
7. The Secret Garden – 25‑seat, seasonal
In a garden behind a tea shop on Chelsea, the Secret Garden opens from 4 pm to 11 pm during spring and summer. The menu features a floral gin spritz for £10. The bar’s seating is a mix of benches and folding chairs. The seasonal closure means you can’t visit in winter, which limits repeat visits.
How to find these bars without a treasure map
Use a simple strategy: look for a door that looks like a regular shop, check the opening hours on the sign, and ask the staff for a recommendation. Most hidden bars will give you a “welcome” nod if you mention the name of the bar you’re looking for.
When a night out turns into a game night
After a few drinks at The Vault, I found myself scrolling through my phone, looking for a quick way to test my luck. That’s when I stumbled upon the ninewin online casino, which offers a range of casino games that can be played from home. The platform is straightforward, with clear payout times and a variety of bonuses that match the excitement of a hidden bar.
Final thoughts
London’s hidden bars are more than just a novelty; they’re a chance to escape the crowds and enjoy a drink in a setting that feels private. Each venue has its own quirks, but none of them are so restrictive that you can’t enjoy a night out. Try one of the spots on this list next weekend, and you’ll discover that the city’s best secrets are often just a door away.
