Mandorong Sikdang is a restaurant in Seoul that serves Jeju-style gogi-guksu and dombe-gogi. It also offers gukbap with pork fat, myeolchi-guksu, and bibim-guksu, and a double portion of gogi-guksu costs no extra. Food comes out soon after ordering, and the space is underground. Parking is hard to find, and the sundae is wet and has an old feel.
