Examine the perfectly ordinary-looking block of flats in the Chelsea Cloisters until you spot the Mickey Mouse wallpaper, then ring the bell, and hope the bartenders like the look of you through the peephole. Inside, find an odd mix of fantastical/absurd car-boot-purchased decor, strong/fanciful drinks with a huge sharing menu (served in teapots, naturally), and plenty of eye-catching clientele. Gather a gang and try the Sloane Ranger, a delightful combination of green-tea-infused Tanqueray London Dry gin, apple, Miclo Liqueur de Violette, honey, and peach.
