Hotto Bun started life as a restaurant specializing in gua bao (Taiwanese pork belly buns) in Rangsit almost a year ago. Now it's branched out to Tha Maharaj riverside mall as a permanently parked food truck. 

The owners are the chefs behind Spicy Shallot, a Thai and Japanese restaurant in New York, and here they add a few fusion twists to the popular soft bun snacks (from B65).

Aside from the classic braised pork belly filling, the crispy battered chicken option comes dashed with spicy mayo and seaweed flakes, somehow resulting in a fusion Japanese flavor. There's also a tasty tempura fish choice, while fries set you back B55.
