Buzi Cafe sits on Yongkang Street in Taipei's Da'an District and is a small coffee shop selling single-origin coffee, espresso, and milk tea. The single-origin coffee is acidic, and lattes and brownies are also sold. Customers sit at the window bar table or on the stools outside, then order and pay at the counter, and the coffee can take a long time to come out. There is no toilet inside the shop, and the windows are kept open so the air conditioning is weak.
