It should be the North Market Food Street in Huanggu District. Then take a few stops to the West Tower, where there is a night market.
A must-eat, Sita cold noodles + soy sauce beef + Korean pickles/mixed cauliflower. Jinzhou BBQ + Draft Beer. Laobian dumplings/Haicheng pie/Majia siomai/Huitou (all four have fillings). Li Liangui’s bacon flatbread (personally I think you can eat it or not). Guobao Pork + Sliced ??Pork Slices (one sweet and one salty, a must-try), pan-fried lamb leg (this is very delicious, a hard vegetable), braised pork ribs with pickled cabbage (delicious), mixed chicken rack (personally think the best when mixed) For those who are particularly greedy, eat grilled chicken rack + beer.
For high-end ones, go directly to Lumingchun Hotel.
