Dong-A Naengmyeon is a naengmyeon restaurant near Soonchunhyang Hospital that serves mul naengmyeon, bibim naengmyeon, and mandu. The mul naengmyeon broth includes dadegi, and orders made not spicy are served without the seasoning so diners can adjust it themselves with the sauce on the table. The building's red and blue colors, used for over 40 years, represent spicy and non-spicy, and the hot broth is a side that brings people back three times along with the naengmyeon. The basic broth portion is small and must be requested separately, and the noodles and broth are commercially made with additives, making it costly for the price.
