Yeotnal Hamburger Ritoast is a retro snack shop below Busanjin High School in Choeup-dong, Busan, selling old-style handmade hamburgers, Pikachu donkatsu, and ade. The hamburgers are cooked to order and recall a school-front corner store. Inside, photos and nostalgic objects from the 1970s through the 2000s are on display. The shop's cat climbs onto the tables and is a distraction during meals.
