Ssaengdungine Haemul Son Kalguksu is an old kalguksu shop in Noryangjin, Seoul, serving oyster seafood kalguksu, bibimbap, mandu, and summer kongguksu. The chewy kalguksu comes with oysters and seafood, alongside spicy geotjeori kimchi made in-house. The shop has only four tables, and the couple who run it do the cooking themselves; delivery is also available. It is closed on the second and fourth Sundays, and the mandu filling is on the light side.
