"Opened by chef Daisuke Shimoyama, formerly head chef at two Michelin-starred Umu in Mayfair, Hannah is a Japanese restaurant with quiet European influences. In addition to his role of chef patron here, Shimoyama is also a qualified sake sommelier, which is reflected in the list of rare and unusual sakes served. At lunch time, Hannah offers decent bento boxes, but the omakase menu is the main draw, at £135 per person. The quality of the food served is often outstanding: ideally sit at the bar and admire Shimoyama’s knife skills, as well as faultless sashimi platters and other dishes which change with the seasons. Think tempura monkfish with purple potato and vinegar crisps; deep fried abalone with caviar; cold soba fragrant with ginger; or Cornish spider crab rice with a deep crab sauce, ikura and black truffle." - Jonathan Hatchman
