Rengaya is a Japanese yakiniku restaurant in the basement of Ploenchit Center in Bangkok. It grills beef and pork over charcoal and serves salted beef tongue, hormone yaki, Japanese-style hoe, and fried shrimp. Lunch sets are ordered before 2 PM and come with rice, salad, kimchi, miso soup, tea, and fruit. Grilling smoke lingers strongly in the dining room.
