Dress smartly to fit in with the fashion-conscious 40-somethings who gather here for high-powered business lunches and after-work cocktails. The sleek dining room looks like a setting in a black-and-white movie with its white walls and table cloths, waiters decked out in black with crisp white aprons, and liberal use of steel and glass architectural details. Bringing the scene to life are warm woods (including 50,000-year-old swamp kauri timber from New Zealand used for some of the tables), jazz playing softly in the background, and an open kitchen briskly turning out orders. But what I most love about this place is the bar, separated from the restaurant by an open-air catwalk suspended over an infinity pool and offering poster-perfect views of the city's skyline from its outdoor terrace with comfy sofas. As for the menu, Wagyu beef reigns supreme, though there are plenty of other yummy choices like the lamb chops or the slow-cooked Aomori duck breast. Weekday lunches and weekend brunches also come highly recommended, but even if you don't dine here, a drink on the outdoor terrace will make Tokyo seem like the most relaxing place in the world. The bar is open until 2am (Sunday until 10pm).
