Muika is a cafe in a residential area near Lotte Mart Jeju Branch in Jeju, selling iced Americano, cheonggyul Americano, and matcha. The wall facing the road is all glass, and the white interior holds light brown tables and chairs. Orders are placed at the counter inside, and trees are visible through the window at the back. One group was there at the time of the visit, and it soon became full.
