Purl, opened in Mayfair’s Marylebone in 2010, is one of London’s pioneering speakeasy-style cocktail bars and remains a benchmark for creative drinkcraft. Set in a vaulted underground cellar at 50–54 Blandford Street, the space is moodily lit, with exposed brick, dark wood panelling, leather Chesterfield sofas, and intimate cubbyholes—perfect for clandestine conversations and cocktail drama. Cocktails at Purl are theatrical. Ingredients such as fog, airs, foams, and food pairings elevate each drink into a sensory story. Building on seasonal produce and zero-waste philosophy, bartenders turn scrap fruits and herbs into house-made syrups and shrubs. Standout drinks include the smokey “Mr Hyde” and the “1806” featuring marzipan liqueur, dry ice, wood smoke, and playful presentation. The bar is the brainchild of renowned innovators behind Worship Street Whistling Shop and Dach & Sons. The menu changes regularly, mixing prohibition-era inspiration with contemporary culinary flair. Purl offers live jazz on Wednesdays and hosts cocktail masterclasses for guests keen to delve into the craft of mixology. While most visitors rave about the creativity and ambiance, some note occasional slow service and noise levels during busy nights. Booking ahead is highly recommended—though walk-ins may be seated if space allows—and lovers of speakeasy secrecy will find Purl delivers both mystery and mastery.
