Pot_R is a cafe in a Japanese-style house on the old port street near Chinatown in Incheon. It serves patbingsu, danpatjuk, and Nagasaki castella, and the patbingsu uses old-fashioned water ice rather than milk ice, topped with red bean. The three-story wooden building is the former Daehwa Trading Office, Registered Cultural Heritage No. 568, and the tatami rooms on the second and third floors are used by group reservation. Menu items sell out depending on the time of day, so orders are sometimes not possible.
