Jjajang Sanghoe is a Chinese restaurant near a university district in Seoul that serves jjajangmyeon, jjamppong, and tangsuyuk. The jaengban jjajang is nutty, spicy, and pungent, while the jjamppong has a chadol base with seafood for a heavy yet refreshing flavor. The place opened around 2015, and customers order at a kiosk, then pick up and clear their food on the tray themselves. The interior is dark and worn, which is a drawback for people sensitive to cleanliness.
