Obok Sundaeguk is a restaurant in Naebalsan-dong, Seoul, that serves sundaeguk made with sundae and offal. The sundaeguk comes with diced vegetables mixed in by default, and the sundae set includes tender meat and sundae together. You can choose the contents as sundae only, without sundae, lean meat only, or gopchang only, and chives are served on the side. The kimchi is disappointing.
