Olgaengi Nara is an old restaurant near Boramae Station that serves olgaengi haejangguk, olgaengi sujebi, and olgaengi manduguk. The clear freshwater snail broth comes with plenty of buchu and mallow, along with side dishes such as kimchi and kkakdugi. It opens at 5 a.m., and a wait forms during the lunch peak. Side dishes can be refilled, and the amount of olgaengi is on the small side.
