Jinju Sikdang is a Korean restaurant in Bongnae-dong 1-ga, Yeongdo, Busan, serving one dish: a mackerel haejang-guk with ugeoji and doenjang. The soup comes with rice in a naengmyeon bowl and kkakdugi in a brass pot. It opens at 5 a.m. and closes at 1 p.m., and the single menu means the haejang-guk arrives once you sit down. The soup carries the fishy smell typical of mackerel.
