As the Jason Atherton empire advances toward world domination, the Michelin-starred chef's latest opening is already dominating one world capital. City Social looks out over London from the 24th floor of Tower 42. The dramatic height is a rarity in London's city, and the first thing guests notice when they exit the lifts and catch a glimpse of the iconic Gherkin skyscraper. Atherton worked with Russell Sage Studios on the interiors, keeping things simple and elegant so as not to distract the eye. Sage has given it an updated art deco feel, with rosewood panels and herringbone floors accented with brass, chrome and smoky glass. An open kitchen at the centre of the dining room serves a best-of-British menu by head chef Paul Walsh - this spring it features asparagus salads, roasted quail breast, Lincolnshire rabbit sausage and Dorset John Dory with mussels. Award-winning mixologist Gareth Evans runs the 85-seat bar, pouring spirited cocktails like the '99 Problems But a Birch Ain't One': Somerset three-year apple brandy cut with birch syrup, lemon juice and mandarin.
