Neungdong Guksi is a kalguksu shop in the back alleys of Gunja that serves Neungdong Guksi, yukgaejang kalguksu, and bibim guksu. Thin, soft noodles are served in a thick, rich sagol broth, and diners can add dadegi and chili seeds for seasoning. Perilla leaf muchim, cabbage kimchi, and chive muchim come as basic side dishes, while gochudajim and seasoning sauce are taken separately. The portions of Neungdong Guksi are not large.
