XEX TOKYO/Teppanyaki An is a teppanyaki restaurant on the 13th floor of Daimaru Tokyo, directly connected to Tokyo Station. The meal moves from salad and an appetizer to clams, white fish, scallops, beef, and garlic rice. A chef assigned to each table cuts and grills the meat in front of the diners, and dessert is served at a window seat overlooking Tokyo Station and Marunouchi. Staff service is uneven, and servers sometimes clear plates without speaking.
