Gohyangjip Son Kalguksu is a noodle shop in Godeok-dong, Seoul, serving kalguksu with clams alongside mandu and sujebi. Each day it prepares geotjeori by mixing it in a mortar, and in summer it offers kongguksu made with finely ground broth. The shop has been in operation for more than 20 years. The taste has changed from what it once was.
