Takamitsu is a reservation-only sushi restaurant in a residential area of Naka-Meguro, Tokyo, with seating centered on a counter. It serves several kinds of sea urchin for comparison and dishes with white truffle and caviar. A weekday 9 p.m. reservation had no wait, and Hermes, Louis Vuitton and Baccarat items sit on the counter and shelves. New reservations are hard to get.
