Cafe Cotton sits where the Tenjin Station underground shopping arcade connects to the basement of the Tenjin Building. The small cafe serves coffee and desserts in an old-style kissaten atmosphere, brewing by hand drip rather than machine and pairing the coffee with cheesecake and coffee jelly. There are bar seats and five small tables, and payment is accepted only in cash or by PayPal QR. The coffee portions are on the small side.
