Keunmam Halmae Sundaeguk is a restaurant in Seoul that serves sundaeguk as its main dish alongside about 20 other Korean dishes made with pork byproducts, including naejangtang, suyuk and gopchang jeongol. The sundaeguk is eaten with a seasoning sauce and perilla seed powder, and takeout is available at night. The restaurant originally operated 24 hours a day and serves both solo diners and groups of three to four. The sundaeguk has a fishy smell and the food tastes poor.
