When you have ten yuan in your pocket and have to eat quickly, a noodle shop like this one on Qingyang Da Dao is exactly what you need. Unfortunately these places are getting rarer and rarer in the more developed areas of the city.
A very generous one liang serving of su jiao za jiang noodles, a side order of boiled cabbage, and a gratis bowl of noodle water to drink completely hit the spot for a total of four yuan. (This kind of noodle is 素椒杂酱面, 'red-cooked beef noodles' in the post title is the name of the shop.)
