Hansung Kalguksu is a kalguksu restaurant in the Bamgol area of Sokcho. It serves jang kalguksu, haemul kalguksu, and son kalguksu, with musaengchae and kimchi on the side. The restaurant opens at 10 a.m., and customers order at a kiosk, then pick up their food at the serving counter when their number appears on the display board. Water, side dishes, and tray return are all self-service, so the wait is long during lunch hours.
