Yeongil Son Kalguksu is an old restaurant in the middle of Busan’s busy streets, serving kalguksu (knife-cut noodles) and bibim kalguksu. The kalguksu noodles are chewy, the broth is rich, and the sauce coats the bibim kalguksu well. The restaurant also serves gimbap, dangmyeon, and spicy noodle dishes. When customers say they want to pay by card, the staff frown and demand a cash transfer.
