Aiyu Zhi Meng You Xiancao is a traditional dessert shop on Tonghua Street in Taipei's Da'an District that sells handmade aiyu and xiancao. The xiancao mixed shaved ice comes with toppings such as taro balls, fenyuan, and red beans, and the aiyu and xiancao are made by hand every day. On summer evenings the line is long and indoor seating is limited, so many customers get takeout. Staff service is uncomfortable.
