Riyoriyo Coffee is a blue-themed cafe near Isu Station in Seoul that serves signature lattes, cakes, and croffles. The signature latte is nutty and sweet, and black sesame menu items and croffles can be ordered with up to three scoops of ice cream at no extra charge. A dog greets customers, and the ordering area has postcards that can be decorated with dog drawings. The space is small, so it gets crowded when there are many customers.
