Ondal Tojong Sundaeguk serves clear Seoul-style sundae guk and suyuk near Exit 1 of Munjeong Station in Munjeong-dong. The broth is a clear sagol base, not thick, and holds sundae and head meat, seasoned with dadegi, cheongyang gochu, buchu, deulkkae garu, and saeujeot. At lunch there is a wait, but office workers leave quickly so tables turn over fast. Even when ordered as a special, the amount of sundae is small.
