Tihaus Sai is a quiet tea house in Josu-ri, Hangyeong-myeon, on the west side of Jeju, and it serves tea rather than coffee. The menu describes the flavors of the traditional teas so customers can choose, and desserts are sold alongside the tea. The single-story space, converted from a tangerine warehouse, holds only about three or four groups at a time. Parking fits about two cars and there is no separate space for a wait.
