This small jiaozi chain from Beijing opened an outlet at Marina Square about a month ago (6 Raffles Boulevard #03-128, 8655-7158). It looked promising, especially given that they made dumplings to order. The best thing was the chewy skin, the texture which also shone through in two of the noodle dishes that we ordered.
Jia He Xing adds to the range of affordable dining options in Marina Square. Those who like boiled dumplings should like Jia He Xing.
