The unmanned cafe is, by definition, a cafe without a waiter. We need to take the cup to fill with coffee, tea, honey dumpling tea, etc. After eating, we consciously put the money for small snacks and coffee into the small box and clean the cup according to the price list. We went to the second floor and faced the sea outside. It was really comfortable. By the way, Jeju Island is naive and beautiful, and you can see the plane above anytime, anywhere.
