Yakiniku Master Shoutaian (Matsusaka Wagyu) is a yakiniku restaurant on the third floor of Hotel Nikko Bangkok in Thong Lo, Bangkok. It serves Matsusaka wagyu and A5-grade wagyu grilled over charcoal, and also offers a buffet course. The buffet requires advance reservations, with 90 minutes for ordering and 120 minutes for the meal. Side dishes are useful because eating a large amount of wagyu can become rich.
