Gwangseok Sinchon Kalguksu Main Branch sits near Sinchon Station Exit 5, across from Sinchon Artreon, and serves mushroom shabu-shabu alongside kalguksu. The meal moves from a spicy dadegi broth with beef, oyster mushrooms and water dropwort into knife-cut noodles and then fried rice. Noodles and mushrooms are refilled without limit, and tables turn over quickly in the evening. In the evening the serving pace is fast enough to disrupt the flow of the meal.
