"Named one of San Diego’s 23 Essential Chinese Restaurants, this fast-casual chain from Los Angeles serves dishes from provinces in China that are not commonly found on menus in the U.S. including liang pi, cold noodles dressed in chili oil, cucumbers, and peanuts made in limited quantities daily, and roujiamo, a flatbread stuffed with pork or beef, hail from the Shanxi province. The Guilin soup from Southern China with beef shank, lily flowers, and sour bean rice noodles is another top-seller, as well as spicy won ton soup, mapo tofu, and Mongolian beef."
