Windstone is a cafe in Gwangnyeong, Aewol, Jeju, next to Gwangnyeong Elementary School, housed in a renovated old building and selling coffee alongside books. The strong latte is rich and nutty, and the almond latte is nutty and sweet. The indoor seating and tables are few, so there is not much room to sit and stay. The book selection is small, which makes it a limited choice for a book cafe aimed at reading.
