Twins Liangpi Limited is a small food shop in Mong Kok, Hong Kong, selling Sichuan-style liangpi, naengmyeon, and wontons. The signature liangpi mixes cucumber, peanut, peas, and cilantro with a sweet-and-sour sauce, and customers choose their toppings and spice level. Orders are placed and paid for directly by QR code, and on a weekday at 3 p.m. the food came out quickly. Seating is small, with only wall-side spots, so the eating area is cramped.
