Cocktail Bar Hire in Chelsea, London

When comparing cocktail bar venues in the capital, Barts doesn’t shout for attention – it lets the right people find it. Rooted in 1920s Prohibition-era glamour, discover a quietly indulgent escape from modern London, where rules feel optional and time slips easily out of reach. The mischief is in the details: low, flattering light, vintage interiors, jazz-infused energy and cocktails that arrive with a knowing smile. Early evenings invite hushed conversation and raised eyebrows; later, the room loosens, the tempo lifts and the night takes its own direction.

Nothing here feels staged. Events unfold naturally, elegance giving way to energy without ever losing their edge. Nostalgic, a little rebellious and very much alive, Barts leaves guests with the sense they’ve stumbled upon something they probably shouldn’t talk about – but absolutely will.

For full private hire, the space becomes your own closed-door speakeasy for the evening. The bar is yours, cocktails flow to suit the mood, and the atmosphere builds naturally from relaxed conversation into a lively, late-night rhythm. It’s a popular choice for hen party cocktail bar hire, birthday party cocktail bar hire, and cocktail bar hire for weddings, where guests can settle in and stay awhile. Semi-private hire offers a more flexible alternative for smaller groups, providing a dedicated area within the venue while still enjoying the buzz of one of the most distinctive bar venue hire London options.

Full venue hire provides complete privacy and control over the space, making it ideal for hosts who want an immersive, uninterrupted event. Exclusive hire allows the entire bar to be tailored to your event flow, ensuring guests can move, mingle, and enjoy the atmosphere without restrictions.

Best suited for: Corporate events and brand launches. Large birthday parties and social celebrations. Wedding receptions and milestone events.

Maximum standing capacity: up to 80 guests

Drinks sit at the heart of every event at Barts, and each menu starts with a conversation. Hosts can discuss different cocktail styles, flavours, and presentations with the team to ensure the drinks reflect the tone and purpose of the occasion. Alongside bespoke creations, the venue offers an extensive drinks menu inspired by its speakeasy heritage, giving guests plenty of choice throughout the night. From signature serves to fully customised cocktails aligned with a brand or theme, the focus is on delivering a drinks experience that feels thoughtful, playful, and memorable.

Chelsea’s reputation for style and heritage pairs naturally with the venue’s vintage speakeasy aesthetic. Inside, low lighting, period-inspired details, and carefully curated visuals create a setting that feels cinematic yet welcoming. The 1920s influence is present without being theatrical, adding warmth, character, and a timeless quality that makes events feel indulgent rather than overstated. It’s a space that stands out not by being loud, but by being richly atmospheric.
