Sungdeok Bunsik is a school-front snack shop next to Jeongneung Elementary School in Seoul, selling gimbap and tteokbokki. It serves basic tteokbokki and instant tteokbokki, and the gimbap has a savory taste. Adults make up more of its customers than students, even though it sits in front of an elementary school. The flavors follow an old style and differ from current snack shop food.
