The name of this restaurant means “grandma’s noodle soup.” Opened in 1958, the restaurant serves guksu made from a traditional recipe handed down to grandma’s daughters. While the restaurant looks like an ordinary snack bar, it attracts crowds of customers because of the wonderful flavor of its guksu. The secret lies in a mouthwatering, delicately spiced seafood broth, as well as tender, hand-made noodles and mildly flavored tofu. A bowl of guksu is the perfect snack, and the service is also great.
