Kitty Fisher's
Located in Shepherd Market, in the heart of Old Mayfair, and named after a famous good-time girl of the mid-18th century who used to frequent the area, Kitty Fisher’s stands as the single standout restaurant success of 2015. Coproprietor Oliver Milburn runs the bar with the charm and suavity only an actor and old Etonian could muster. Although the atmosphere is classic old-London bohemian, the food from former Best Young Chef of the Year Tomos Parry is at the cutting edge—the menu has featured lots of charring and ash-focused dishes, plus a rib-eye of 12-year-old Galician dairy cow that’s been called the finest steak ever served in London—this is post-hipster East London's version of 21st-century gastronomy for grown-ups.
