Cactus Tapioca and Black Sesame Tapioca had unfortunately sold out for the day. Taro Tapioca Milk Tea and OneZo Oolong Milk Tea were chosen instead.
The waitress was an exceptional addition to the experience: not only was she polite, attentive, and intuitive, she was kind enough to provide me with a charging cable (I had forgotten mine at home) upon request.
