Shanghai Ren Jia is tucked at one corner below a HDB flat at Ang Mo kio. There is not much interior and exterior design to talk about and Shanghai Ren Jia only has about seven tables in their shop.
They offer mainly small or dim sum dishes with limited selections of noodles. The boss is super sociable and likes to chit chat with his guests and to share some stories behind his menu and to give recommendation on the food that you are ordering.
This place is famous for their Popiah actually but i like their Sheng Jian Bao best.
