Ujin Gosari Yukgaejang is an annex restaurant next to the main branch of Ujin Haejangguk in Jeju, serving gosari haejangguk and momguk (pork and gulfweed soup). It operates as the same establishment as Ujin Haejangguk, so mung bean pancakes can be ordered as well. Reservations are made on-site through Catchtable, and there is an attached parking lot where customers can wait in their cars. There is almost always a wait, and entry can take up to two hours.
