Yeosudaeck is a Korean restaurant in the market alley of Gyeongnidan-gil at Itaewon Jeil Market, serving steamed, grilled, and braised fish with drinking snacks. It uses deokja and other fish brought in directly from Yeosu, and deokja-jjim is its representative dish. The owner is from Yeosu, and the side dishes include soy-marinated crab seasoning and gim. The seating is limited, so the restaurant is often full, and going with several people makes it easier to try a range of dishes.
