Pat Janggun is a small cafe in Daejo-dong, Eunpyeong-gu, Seoul, near Gusan Station, serving patbingsu and patjuk. It makes its own pat with domestic red beans, which is mildly sweet and soft with a grainy texture, and serves ice-based bingsu rather than milk-based bingsu. The menu also includes strawberry bingsu and hobakjuk alongside patbingsu and dongji patjuk, and many customers order takeout. Seating is limited.
