Sio is a Japanese-style izakaya in an alley of the Chungmuro university district, serving draft beer with snacks such as fish cake soup and yellowtail hoe. The okonomiyaki comes topped with a heavy sauce, and the yellowtail hoe set is served with perilla leaves and seaweed. It sits across the alley from a street where many Dongguk University students go, and inside there is a video-style photo zone where you can take pictures. The karaage fried chicken feels like a snack.
