Here we have two Londons. One is noisy and bright – the Big Ben, the red buses, the Thames walks. The other one is less noisy. Quirkier. Deliciously mysterious. It is found behind bookshelves, via fridge doors, under old railway arches and in what appears to be an abandoned toilet.

London is the city of secret bars – secret speakeasies that can make an average night look like a movie. This is more than a list blog. It is a passport to the London of the thrill-seeker, tailored to the individuals who feel that the best things in life are the ones whispered rather than shouted.

London's Secret Side: Beyond the Landmarks

London's hidden bars are a testament to the city's enduring spirit of innovation and theatricality. They are meticulously crafted environments, each with its own story, designed to transport you and offer an experience far beyond just a drink. This guide invites you to step behind the curtain and discover the London that only a select few truly know. Let’s step behind the curtain.

1. Evans & Peel Detective Agency – Earl’s Court

Vibe: 1940s Private Detective meets Smoky Jazz Lounge

Your First Clue: The Detective's Office

Through a frosted glass window in an old door, the office of a detective right out of a Raymond Chandler novel is revealed. Dim lighting. Scattered work desk. A “detective” in suspenders questioning you on the reasons of your arrival. Pro tip: invent a false case. This initial encounter is an immersive theatrical experience, setting the tone for your clandestine evening.

The Big Reveal: Behind the Wall

Then the magic comes. A wall opens up and you find yourself in a secret speakeasy with candles casting their light upon exposed brick walls and smooth jazz filling the atmosphere. Get the “Smoked Old Fashioned,” which comes with a bell jar full of thick smoke, and have tapas as you deliberate on your case. The jazz often features live musicians, adding to the authentic 1940s vibe.

Where to look: Tucked away near Earls Court Station. No signage. Just confidence.

Finding Your Way: Confidence is Key

Finding Evans & Peel is part of the adventure. The lack of overt signage reinforces its hidden gem status, rewarding those with a keen eye and a bit of nerve.

2. Cahoots – Soho

Vibe: WWII Blitz Bunker Turned Boozy Tube Station

All Aboard for a Post-War Party!

The spirit of London is up, the war has ended and you are going to a party. Underground. Literally.

From Air Raid Shelter to Retro Haven

Cahoots is a former 1940s air raid shelter, now a retro haven. Expect vintage Tube carriages, booths, bunting, ration-book menus, and bartenders in RAF officer and WREN uniform. Every detail contributes to the immersive illusion of a clandestine tube station party.

Drinks Served with a Twist (or in a Boot!)

You may receive your beverage in a tin mug, teacup, or even a boot (seriously). How about The Vera Lynn, floral, bright, and guaranteed to get you feeling like you are swing dancing in Piccadilly. The staff are fully in character, enhancing the wartime experience.

Insider tip: It’s in Kingly Court. Look for a staircase with a sign that looks like London Underground graffiti. Blink and you’ll miss it.

The Subtle Entrance to a Grand Party

The Secret Password: "I'd like to see the Mayor."

Walk into The Breakfast Club café. Order a pancake stack. Then lean in and whisper: "I'd like to see the Mayor." This playful password is your key to an unexpected adventure.

Through the Fridge Door: A Whimsical Portal

Next thing you know, you’re being ushered through a Smeg fridge. Yes, a fridge. Push through, descend a staircase lit by flickering bulbs, and welcome yourself into one of London's most iconic hidden bars.

Inside the Feline Lair: Neon and Nostalgia

Low ceilings, mismatched furniture, glowing cat signs, and a buzzing crowd fill this quirky subterranean space. Try the “Tommy’s Margarita” – smooth and dangerously drinkable, perfectly complementing the bar's casual cool.

Inside the Bunker: A Chemistry Lab of Mixology

Slide into a WW2 bunker replica. Don a military jacket. Use a vintage radio and a decryption sheet. Your answers are relayed to a “chemistry lab” of bartenders who’ll mix your mystery drink. The result? A cocktail crafted entirely to your taste—no menu, just alchemy.

Access code: Located inside the Chelsea Funhouse. The sign outside is subtle. The experience is not.

Finding the Funhouse: Subtle Outside, Unforgettable Inside

5. Discount Suit Company – Spitalfields

Vibe: Tailor’s Basement with a Splash of Sinatra

You’ll feel like you’ve stumbled into a secret jazz club in 1950s Chicago. The menu is small, the service is stellar, and the cocktails are chef’s kiss. Try “The Cravat” – a bittersweet beauty with notes of cherry, smoke, and style. The atmosphere is perfect for hushed conversations and contemplative sips.

Look for: Faint signage and an old wooden door near Petticoat Lane. If you feel like you’re trespassing, you’re on the right path.
