Ganggu Sikdang is a simple eatery in Tongyeong Jungang Market. It serves an oyster course, a mussel seaweed soup sotbap set meal, and a gejang set meal, and the dolsotbap is mixed with the gejang. From the second-floor window you can see Ganggu Port, and the seaweed soup is available for takeout. The side dishes are less satisfying than the seaweed soup and sotbap, and the jeonbuchim comes out cold.
