When you hear “hidden bar” in London, think of a speakeasy that opens with a whispered password, a cocktail that arrives on a slate of glass, or a secret corner tucked behind a bookshop. The real charm is that you discover it without a Google map, and the experience feels like a private club you’re lucky enough to be invited into.
1. The Attic – Above the Old Bookshop
Located on Tottenham Court Road, the bar sits three flights above a 19th‑century bookshop. The entrance is a plain door with a brass keyhole. Inside, the décor is a mix of reclaimed timber and brass lamps. Their signature gin‑based “Attic Tonic” takes 12 minutes to prepare, so you’re rewarded with a slow‑burning conversation.
2. The Vault – Beneath a Brick‑Wall Café
In Clerkenwell, a café’s back door leads to a vaulted room lit by a single chandelier. The menu is a rotating list of craft beers, but the real draw is the “Vault Stout,” a 9% ABV brew that takes 48 hours to mature in oak barrels.
3. The Cell – Inside a Disused Post Office
At Old Street, a former post office’s basement houses The Cell. The bar is accessed by a hidden lever behind a newspaper rack. The cocktail menu is curated by a local mixologist who uses ingredients sourced from the city’s street markets.
4. The Hide – Near a Quiet Garden
Near Hampstead Heath, a small door in a brick wall opens into a dimly lit space. The walls are lined with vintage vinyl records. The “Garden Whisper” is a gin‑based drink that includes a sprig of rosemary grown in the bar’s own herb garden.
5. The Nook – Inside a Bookshop’s Backroom
At a bookshop on Bloomsbury, a hidden door behind a shelf leads to The Nook. The bar’s décor is a collage of literary quotes. Their “Page Turner” cocktail is a layered drink that changes flavour as you sip.
6. The Alcove – Between Two Pubs
In Camden, two pubs flank a narrow alley. Behind a wooden crate in the alley lies The Alcove. The bar serves a “Camden Cooler,” a citrus‑infused gin that takes 15 minutes to chill in a copper pot.
7. The Backroom – Inside a Vintage Record Store
On Brick Lane, a record store’s backroom hides The Backroom. The bar’s walls are covered in vinyl sleeves. Their “Spin‑Off” cocktail is a rum‑based drink that comes with a small vinyl record as garnish.
8. The Lair – Hidden in a Theatre
At the Royal Court Theatre, a side door leads to The Lair. The bar’s lighting is dim, with a single spotlight on the bartender. The “Curtain Call” is a bourbon‑based drink served with a theatrical flourish.
9. The Secret – Behind a Paint Store
In Shoreditch, a paint store’s back door opens to The Secret. The bar’s interior is a collage of paint cans and art supplies. Their “Palette Punch” is a vibrant mix of tropical fruit juices and a splash of absinthe.
10. The Speakeasy – In a Disused Railway Station
Near Euston, a disused railway station’s platform hides The Speakeasy. The bar is accessed by a brass key hidden in a railway ticket box. Their “Ticket to Ride” cocktail is a whisky‑based drink that comes with a small ticket stub as a prop.

How to Find Your Next Hidden Bar
Most of these spots don’t appear on mainstream guidebooks. A good rule of thumb is to keep an eye out for doors that look out of place – a plain door with a brass keyhole, a door behind a bookcase, or a door that looks older than the building itself. Once inside, the bartender will usually give you a quick rundown of the house specials. If you’re unsure, ask for the “signature drink” – it’s the bar’s best representation.
Why the Secret Matters
Hidden bars offer a pause from the city’s constant buzz. They’re places where conversation flows without the noise of a crowded venue, and the drinks feel like a personal secret shared between you and the bartender. The experience is a reminder that London still holds pockets of mystery, waiting for curious souls to uncover them.
