Chungmuro So is a bar in Inhyeon Market near Chungmuro Station in Seoul that serves Cass draft beer and simple snacks. Cass draft beer is the focus, with a clean and smooth taste, and Suntory Premium Malt's is also available. The space is very small and gets crowded, and there is a branch with seating nearby. All seats are standing, so staying for a long time is difficult.
