Chun Sui Tang is a Taiwanese cafe in the Tenjin underground mall in Fukuoka's Chuo Ward, serving Taiwanese dishes, milk tea, and desserts. It offers tapioca milk tea, douhua, lurou fan, and dan dan noodles, with a choice of sweetness level and amount of ice. A morning set is available from 10 to 11 a.m., orders are placed by QR code, and drinks can be taken out. The space is small, and seats run short on weekends and at lunch, so waits get long.
