Seongsan Badapunggyeong is a restaurant near the port and sea in front of Seongsan Ilchulbong in Seogwipo, serving grilled hairtail and braised hairtail. Ordering the braised hairtail brings a whole grilled hairtail as well, and there is also a set that includes braised mackerel. It opens in the morning, offers self-refills of seaweed soup and side dishes, and has a parking lot in front. The seasoning does not soak deeply into the fish, so anyone who prefers strong, assertive flavors will find it plain.
