王家沙 Wang Jia Sha is another old school Shanghai-ese eatery, but does mostly small food / snacks rather than meals. It is also on West Nanjing Rd, near Mei Long Zhen.
At the ground floor, it sells take away buns, wontons, Suzhou style mooncakes (my aunty recommends meat filling ones), various rice desserts, zong zi… However some of them do not belong to WJS, even though they might operate right next to the WJS kiosks. Be wary of these and follow the crowd.
Upstairs is their sit down restaurant. The food here is just average, and I’ve heard it more than once that it relies on the legacy of its brand name rather than the quality of the food.
Buy some takeaway treats at WJS, located at 805 West Nanjing Rd.
