Muan Susan is a raw fish and seafood course restaurant about a four- to five-minute walk from Exit 10 of Sadang Station. The course determines the types of hoe and seafood served, and it also includes san-nakji, miyeokguk, braised flatfish, and grilled mackerel. Branches 1, 2, and 3 sit next to each other, expanding the seating, and courses and party size are booked in advance. The space is not large and has almost no interior design, resembling a raw fish restaurant in a market neighborhood.
