Cafe Sion sits on a steep hill in Goejeong-dong, Saha-gu, Busan, and occupies an entire building. It runs a kids zone on the basement floor with bakery and cookie making, rabbits, and sand play, while the second floor is a no-kids zone. A parking attendant is on duty in the lot, and the first-floor outdoor seating has a mini pool and a fire pit area for roasting marshmallows. The road up to the cafe is very steep.
