Umu

Take a Michelin star chef, an intimidatingly swanky location, and a near theatrical take on detail and decor, and you have Umu, one of the shining jewels in Mayfair's menagerie of high-end Japanese luxury restaurants. Head Chef Yoshinori Ishii has been displaying his flair for exquisitely delicate Kyoto-inspired cuisine since taking over at Umu in 2010, and he has curated an experience which will leave both Japanese-food-pedants and poshies in awe. For £45 a set lunch will get you a selection of fresh sashimi with kinshi and shiitake, or go a la carte and try Ibushi smoked "a la minute" with plum-shiso for £28.
