Decent, mid-size Gansu eatery in Hongkou, near Luxun Park, best known for their "niu da wan" (big beef bowl), a ginormous bowl of Lanzhou la mian that goes for 98rmb and could feed two-to-four people. They're a proper Gansu-style noodle joint, so they give you like nine options for noodle thickness. They also serve lamb skewers and, naturally, cold Wusu beers from the fridge.
