WHAT'S THE DRAW: Zuma's Kyoichi Kai brings his brand of authentic but modern sushi and barbecue, along with an all-Japanese kitchen staff, to a stunning mansion-turned-restaurant in the heart of Belgravia.

WHAT TO DRINK: Want authenticity? Stick with Japanese whiskies, sake, and 'twisted' cocktails infused with Japanese flavours by the in-house mixologist.

WHAT TO EAT: Superb marinated amiyaki sirloin arrives beneath a pile of fresh, crunchy vegetables, and you can't go wrong with pretty much anything from the traditional sushi bar, but black cod with fennel miso is the standout performer. Inventive, and utterly delicious.
