Deungchon Shabukalguksu Hongdae Branch is a restaurant near the main gate of Hongdae that serves mushroom spicy kalguksu and shabu-shabu. The meal starts with minari and beef in a spicy broth seasoned with gochujang, then moves on to kalguksu and bokkeumbap. Orders start at two servings, and the kalguksu menu uses udon noodles that do not soften easily. The interior is cramped, with old tables and chairs, and several fans run in summer.
