"Sake No Hana, St Jamess. This chic Japanese restaurant has incredible interiors by architect Kengo Kuma with bamboo that climb the walls like a futuristic forest. The haute-cuisine level of Japanese food, dishes too are little sculptural marvels and a modern take on traditional kaiseki. Sake bar, Ni Ju San, has an extensive sake collection, and hosts sake and umeshu —traditional plum wine —appreciation classes for those who like to learn as they drink."
