Sister restaurant to New York's Nobu (and now with 20 locations worldwide), this classy, modern establishment is the place to see and be seen -- and you can count on being seen, since the efficient, black-clad staff yells "Irashaimase!" ("Welcome!") the moment anyone is ushered into the large dining room. The food, beautifully presented and served one dish at a time, is a unique blend of Pacific Rim ingredients (not quite Japanese) with decidedly American/Latin influences. Sushi and sashimi are served, as well as sushi rolls such as California rolls (with avocado) and soft-shell-crab rolls. Other dishes include the roast fish of the day with jalapeño dressing, sake roasted cod with sansho salsa, baby squid with ginger salsa, wagyu steak with a choice of sauce, and sautéed scallops with wasabi pepper sauce. If ordering is too much of a chore, you can leave your meal to the discretion of Chef Matsuhisa by ordering the omakase, a complete chef's-choice dinner starting at ¥12,000. Nobu has an unlikely location in an obscure office building, but the Hotel Okura across the street and the nearby U.S. embassy assure it a steady stream of moneyed customers.
