Part of the Tinun group of Thai restaurants, Sukhumvit Soi 55 is worth knowing about for their reasonably priced weekday lunch buffet if you happen to be in the neighborhood and hungry. In addition to one main dish of your choice you can help yourself to unlimited servings of a curry and two other entrees, a Thai-style salad and a green salad, one soup, rice and one dessert. Although the selection is quite limited by Tokyo Thai buffet standards, the quality is good and the price is reasonable.
The time limit for the buffet is sixty minutes, and they start to clear the buffet table at 2:30pm. Prices start at Y1100 (depending on your choice of main dish), while food and drink at dinnertime will average around Y2500. Saturday and holiday hours are 11:30-2, 5-9pm (LO), and there's no buffet on those days.
