Gangdaegam Son Kalguksu is a restaurant inside Gupo Market in Busan that serves hand-pulled kalguksu, bibim kalguksu, and mandu. The noodles are pulled to order, giving them a chewy texture, and the broth is mild and cool. Tables turn over quickly, which suits shoppers who want to eat right after buying groceries, and families make up a large share of the customers. The flavors are ordinary rather than distinctive.
