Gaegeum Kalguksu is an old noodle shop just above the Gaegeum Milmyeon Alley in Busan, serving kalguksu, bibim guksu, and kongguksu. The kalguksu comes with its own noodles and broth, and the kongguksu is made by grinding domestic soybeans on site. The restaurant has run for nearly 40 years, uses domestic ingredients for everything, and keeps a short menu of about four noodle dishes. Prices have barely risen, so a meal there is not a burden.
