Jeju Dong Mart is a neighborhood supermarket in Goseong, Seongsan, Seogwipo, selling groceries, household goods, and fruit and vegetables. It also sells small takeout packs of side dishes, gimbap, and local bread and rice cakes. The store has been open around 7 a.m., and it is used as an alternative place to shop when Hanaro Mart is closed. Parking spaces are limited, so parking a car there is inconvenient.
