Sahsya Kanetanaka is the entry level offshoot of exclusive kaiseki (haute cuisine) restaurant Kanetanaka. At lunch (served until 2pm) choose two mains (maybe thin sliced Japanese beef or sea bream) to go with small plates of seasonal vegetables (mushrooms topped with chrysanthemum petals, for example). Dinner (reservations required) is six courses with a little bit of everything.
It's an astonishingly peaceful refuge at the back of a mall right on Omote-sandō, with a garden designed by contemporary artist Hiroshi Sugimoto. In the afternoon visit for tea and Japanese sweets.
