Singapore-based food blog Noob Cook reviews R Burger in Bangkok, Thailand. The Japanese burger chain describes its offerings as "real healthy Japanese burger" and features unconventional combinations such as chicken with plum sauce, and yam and surumi with ginger sauce. There's only one burger actually made of beef on the Thai menu, which doesn't even appear on the Japanese menu; other burgers are mostly made with pork, fish, or tofu, and a special ingredient: collagen. All burgers are served on Chinese-style steamed buns.
