Ruian is a Chinese restaurant near Guseo Station, across from the E-Mart Geumjeong branch, serving cooked dishes, rice dishes, and course meals. Its samseon jjamppong comes with large squid and a clean broth, and bokkeum jjamppong and kkanpunggi can also be ordered. There are group rooms and private rooms where guests take off their shoes, and free parking is available in front of the store and at E-Mart. The jjajangmyeon has a thin, overly sweet sauce and falls short in taste.
