Cheonnyeoncho Son Kalguksu in Seoul serves kalguksu with clams, hand-made dumplings, and patjuk. The clam kalguksu comes with a milky, cool broth and chewy hand-cut noodles. Kongguksu, spicy sujebi, and kimchi jeon are also made in-house, and food takes time to arrive after ordering. The cabbage geotjeori is on the salty side.
