Wang Fu Yuyuan is a dessert shop in Ximen, diagonally across from Ay-Chung Flour-Rice Noodle, selling taro ball shaved ice and douhua. Its main items are shaved ice topped with taro balls and red or mung beans, douhua with lemon syrup, and brown sugar penguoguo. After 3 p.m., taro balls five times larger than the regular ones can be added, and orders come out in about five minutes. There are only two tables in front of the store.
