Cosy is a Mexican restaurant in Jeonpo, Busan, serving Mexican dishes made in a Korean style. Ordering the pork chimichanga, chicken or hot chicken quesadilla, or shrimp tacos gets the dish made on the spot. There is a wait at lunchtime, and the bar seats are comfortable and quiet. The pork chimichanga is a fried burrito topped with sauce, heavy but possibly a little greasy.
