Canteen-style Shanghainese snack house on the corner of Weihai Lu and Shaanxi Bei Lu. Meixin has an illustrious 93 year history, in which they have had plenty of time to refine their recipes for lunchtime grub such as wanton, spring rolls, rice flour dumplings and hand-pulled noodles. Expect to be full for less than 30rmb, but also be prepared to stand in a queue.
