Barts

Barts London's worst kept secret and first speakeasy cocktail bar, hidden somewhere on Sloane Avenue. Pssst… Become part of London’s worst kept secret!
(616)

Somewhere on Sloane Avenue lies Barts, one of London’s first late-night speakeasy bars. Set in the 1920’s prohibition era as the private apartment of the elusive Uncle Barts, friends and associates are invited to join in the bootlegging activities operated by his gangsters. Sneak into the apartment through the black door to gain access to illicit cocktails and top secret shindigs, where you can al

so smuggle drinks into the Secret Garden to evade the cops! Visit our shady associates for secret trysts and covert merrymaking at Barts.
