North of the Yangtze, it’s all about wheat instead of rice. Named after China’s northeasternmost region, this beloved chain serves hand-rolled wheat dumplings stuffed with savory pork or fresh veggies and boiled until the center is juicy. As delicious as the pork jiaozi are, the vegetarian dumplings might be the real stars: Try the tangy mushroom and bok choy dumpling or the green pepper, cilantro, and white cabbage. Warning: Prices here are scandalously cheap, so you're probably going to order...a lot. Locals also love the stir-fried eggplant and potatoes (di san xian) and smashed chicken (xiang su ji).
