Wangjiasha Dim Sum Shop was founded in 1945 and has a history of more than 60 years. "Wang Jiasha" was originally the Wang Jiasha (pronounced she), which is the place name. Because "sha" is a different word for "阿", and in Shanghai, "sha" and "阿" are homophones, and the homophones are borrowed to form Wangjiasha. Although Wangjiasha dim sum restaurant is named after the place, it is famous in Shanghai for its dim sum. It has fragrant, fresh and braised crab noodles, sweet and delicious Babao rice, and fresh and delicious crab noodles, all of which are well-known in the industry.

Wang Jiasha dim sum insists on taking Shanghai dim sum as the basis, and combines the flavors of Jiangnan dim sum to create new things, learn from others' strengths, integrate them in one style, and create one style. Wangjiasha dim sum is exquisitely made and has a unique flavor. For example, the crab noodles Xiaolong, known as the "Xiaolong Steamed Bun King", uses hairy crabs as the raw material. The crab noodles are removed every day and are mixed with broth made by old hens. The skin is Thin filling and fresh soup. The crab noodle glutinous rice dumpling of "Donut King" is unique, with glutinous on the outside and fresh on the inside, and the soup is full. The "Babao Rice King" Wangjiasha Babao Rice is even more glutinous and delicious.
