Small menu, cozy, mom and pop, mostly in the Sichuan/Chongqing direction. I prefer the noodles over the dumplings here, most of all the Yibin noodles with ginger and spice. But actually my favorite dish is the simple (and cheap) ground pork over rice. This is not a full service Chinese restaurant, but definitely worth having in the repertoire. The vegetables are quite good, too, make sure you get the spicy cucumber and a few of the other sides.
