Cheonsa Gopchang Mokdong Branch in Seoul serves grilled beef small intestine and Hanwoo gopchang. The restaurant grills modum gopchang and daechang, and the gopchang has no odor and stays close to the basics. In the evening all seats fill up, so after a reservation there can be a 10-minute wait, and the bokkeum bap is worth eating after the gopchang. Waits happen often.
