Gangneung café souvenir snack that keeps 14 days: Gangneung Sand
Gangneung Sand Main Branch is a three-floor sand cookie dessert café in Seonggok-dong, Gangneung. The writer bought coffee and sweet corn flavor boxes of 10, and since they keep 14 days at room temperature and 30 days refrigerated, they were easy to carry home as the last stop of the trip. Compact and easy to share, they're a solid pick for a Gangneung souvenir snack.
