Mannayo Manna is a cafe and art workshop in an alley near Hamdeok Beach in Jeju. It serves house-made fruit syrup ades, avocado coffee, and handmade tea. A couple runs the place, and the paper glass workshop takes one group each in the morning and afternoon, so advance contact is required and production takes about two hours on the day. It is not directly in front of Hamdeok Beach but set back inside an alley.
