Gupo Janchi Guksu sits behind a parking lot near the shops selling myojong at Gupo Market in Busan. The noodle shop serves on-guksu and naeng-guksu in a light anchovy-based broth, with regular and large portions available. The noodles are pre-cooked, and a photo of Choi Bul-am's visit hangs on the wall. The space in one corner of the parking lot is shabby.
