Dongdaemun Gopchang is a gopchang grill restaurant in Seoul that serves both grilled pork gopchang and gopdori tang. Its signature dish is gopdori tang, made by adding gopchang to flower crab dori tang, and it is eaten by mixing rice into the broth. The gopchang gives off an odor at first, but the cooking method reduces it as it boils longer. The restaurant strongly pushes customers toward cash payment.
