Riri Zhuang Cha A11 Xinyi is in the basement level 1 of Shin Kong Mitsukoshi A11 in Xinyi District, Taipei, and sells tea and bubble tea. It offers buckwheat tea and bubble tea, and customers choose the sweetness level and amount of ice when ordering. Because there is sometimes only one staff member, drinks take a long time to arrive. Orders are sometimes taken late or drinks are given incorrectly while staff are on calls or looking at their phones.
