One of my friends recommended this 包子店 (steamed bun store) nearby because apparently, it was a famous store in the area.
Steamed bun is usually filled with meat and vegetables but they also sell buns wholly for vegetarians. A piece costs 15 NT (~PhP 22.5), and since I hadn't had breakfast yet, I ordered 2 pieces. They're a bit of a mess to eat because aside from the meat and vegetable filling, the inside also contains soup. They're like a bigger version of 小龍包 (Xiao Long Bao). Yum!
The store is located near MRT Zhongxiao Fuxing Exit 2 (捷運忠孝復興站，出口2).
