Peter Kalguksu is a kalguksu restaurant in Geumsa-dong, Busan, serving potato kalguksu and Pyongyang naengmyeon. The potato kalguksu can be ordered with a mini cuttlefish topping, and the onaksaek pajeon comes out thin and crisp. It is open from 11 a.m. to 8:30 p.m., closed on Mondays, and has parking in the yard in front of the shop. Dishes for each person come out separately, so one person can finish eating before the others, and empty tables are cleared late.
