From its bijou space off High Street Ken, this little gem of a restaurant foregoes the culinary pyrotechnics of its nearby sibling, Ocean House, to concentrate on simple, masterfully crafted sushi. Take a seat at the handsome, green-tiled bar or head downstairs to the sleeker monochrome dining room, and indulge in a menu crafted by two Nobu-trained chefs. From the stunning, melt-in-the-mouth Hida Wagyu carpaccio to a beautiful salad of dressed baby octopus, seaweed and cherry tomato, flavours are pin-sharp and ingredients second to none. Also, we urge trusting the chefs when it comes to soy sauce: items such as yellowtail nigiri and yasai maki rolls with asparagus tempura come judiciously brushed with the condiment to avoid drowning out other flavours. Saké is a big deal here, with regular masterclasses on offer, while the pithy wine list has some interesting options – although, like everything here, prices are on the high side.
