Hundertwins is a large cafe on Udo in Jeju, connected directly to the Hundertwasser Park. It serves peanut ice cream, peanut bingsu, Udo donuts, Jeju-related drinks, coffee, and salt bread. The building has full glass windows on the first and second floors, wide seating, and a rooftop garden. On hot days only one air conditioner runs on the second floor, so the indoor space is warm.
