Onjeong Jorim is a Korean restaurant across from the parking lot at Hyeopjae Beach in Jeju, serving braised hairtail and braised mackerel. It offers a menu that combines hairtail and mackerel, along with mackerel grilled over direct heat. The seasoning carries the flavor of red pepper powder and minced garlic, and the well-cooked radish goes with rice. The hairtail flesh is thick and moist, without a fishy taste.
