Compared to the above-mentioned shops, Dingxin will look much shabby, it is opened in the food court in the Mega Plaza, with only a small façade. However, this does not affect the excellent xiaolong, which even hangs a signboard "a popular gourmet dim sum shop bought by Shanghai talents". The chef who made Xiaolong with all his heart was born in the five-star hotel Shanghai Dongjiao Hotel, and was once in charge of the dim sum chef in charge of the state banquet.

The small cages produced by Dingxin are very stable, each with 12 pleats, and the pleats are balanced and consistent, and they look very good. The size of the cage is not too different, and the size is moderate. The crust is not as tough as other shops, with a little softness. The thickness can only be considered moderate, not too thin. When you eat it, the skin is chewy only in the top folds, the soup is not much, the color is refreshing, the meat filling is light, and the taste is tender in the firmness.

There is no service in the food court, and the food needs to be picked up. The environment is also very general, and it will feel very stuffy on rainy days. The only thing to praise is that there are so many restaurants to choose from, and diners can order other dishes to accompany the xiaolong, so it is not recommended for diners to order a heartfelt set meal.
