Oasis 80 is a cafe in the Aewol cafe street of Jeju that sells sand coffee, waffles and bread with kaymak, and tarts. The default espresso is brewed sweet, and an oasis model is displayed in the center of the space. Weekday evenings are quiet with nice lighting, and kaymak milk and sand vanilla latte are also available. When customers crowd in, the counter and pickup area are narrow, so the flow of movement gets tangled.
