Aul is a donkatsu restaurant in the Guui-dong food alley, in front of Guui Station and Gwangjin-gu Office in Seoul, serving roskatsu and chicken katsu. The short menu covers kimchi bokkeum bap, which comes with a fried egg on top, and udon. Sliced cabbage is served with a cayonnaise sauce, and food comes out quickly. The restaurant has held the same spot for over ten years, and the kimchi bokkeum bap portion is large enough that one person may leave some behind.
