Wonjo Busan Yanggopchang in Bangi-dong serves Busan-style gopchang (grilled intestines), makchang (beef abomasum), yang, and chadolbaegi. The ingredients are served without seasoning to preserve their natural flavours. The restaurant is clean and suits an evening drink of soju after work. It is away from Bangi-dong's main street, so you need to find it in an alley.
