Every prohibition party in London at Barts begins the same way, behind a closed door, though no two nights ever play out the same. Step into Uncle Barts apartment with your shady associates and shape the evening as you wish. Bespoke styling, carefully chosen props and subtle nods to Prohibition-era Chicago can be woven through the space, while lighting and décor deepen the illusion without ever feeling staged. The result feels instinctive and lived-in, as if the apartment has always looked this way, quietly waiting for you and your shady associates to arrive.
A True Prohibition Party Experience in London
Step off the Chelsea streets and seek out the hidden door. Murmur the secret password, just loud enough to be heard, and feel the modern world slip quietly behind you. Inside, low jazz drifts through flickering light, and a night reserved for those who know where to look reveals itself. Time begins to soften. Vintage details glow, conversations spark, and a cocktail finds its way into your hand, perhaps poured from a teapot, ice chiming softly beneath the music.
There is no agenda, no announcements. You’re invited to let the atmosphere lead. Energy builds organically, minutes blur into hours, and this 1920s Prohibition-inspired party in London carries you forward without demand or distraction. When the moment comes to return to the street, the city feels sharper, louder, more real. The door closes softly behind you, leaving the sense that you’ve stepped out of something rare and only briefly allowed in.
The Spirit of the 1920s Prohibition Era
Prohibition thrived on contradiction. In the 1920s, restraint existed only on the surface; just beneath it, hidden bars came alive with jazz, hushed exchanges and the thrill of being let in. That same energy quietly lives behind an unmarked door in Chelsea and you’re invited to find it.
What seems to be Uncle Barts apartment soon reveals itself as a speakeasy cocktail bar, one of London’s first, and now its worst-kept secret. Cocktails arrive disguised in teapots, books and unexpected objects, crafted by bootleggers who believe discovery is part of the pleasure. Disguises sit ready too, should the coppers ever decide to come knocking. As the night unfolds, the space shifts. Conversation gives way to movement, the dancefloor comes alive, and the party carries on late into the night. There’s no script to follow, just the pull of the room and the people in it. This isn’t about dressing the part; it’s about slipping into the spirit of the era: intimate, indulgent and quietly rebellious.
Immersive Environment & Sensory Atmosphere
Inside, the shift is instant, you’re in 1920s Chicago, hidden in plain sight. What looks like an ordinary apartment reveals its layers quickly: art-deco touches, vintage curios climbing the walls, and a soft neon glow drawing you deeper in. It feels intimate, lived-in, and just forbidden enough to know you’ve stepped somewhere few ever do.
Listen closely and you’ll hear the soft rattle of shakers and low whispers. Follow your curiosity to the bar, where illicit cocktails are slipped across quietly, meant to be uncovered rather than announced.
A box of disguises sits within reach, not as décor but as an invitation for those who like to blend in. Stay awhile and the room begins to change: neon sharpens, feet move instinctively toward the floor, and the apartment gently lets its cover drop. Nothing is announced. You’re simply welcomed deeper into the night, part of one of London’s most notorious Prohibition worlds.
Entertainment & Interaction That Sets Barts Apart
DJ-Led Atmosphere & Theatrical Touchpoints
The night eases in on a swing of jazz and blues, glasses clinking and the apartment settling into its groove. As the hours slip by, from Thursday through Saturday, the mood begins to change. The resident DJ takes over, the tempo lifts, and suddenly the room feels lighter, louder, and harder to resist. The shift isn’t announced, it’s felt, a slow pull toward the dancefloor that carries the party deep into the early hours. Stay with it, and let the night take you where it wants to go.
