Gwon Guseong Sundae Gukbap is a sundae gukbap restaurant in Cheonan. The sundae gukbap contains both Byeongcheon-style sundae and dangmyeon sundae, topped with minced garlic. It is open 24 hours, and about 8 to 10 cars can park in the lot behind the building. Rice and onions can be refilled continuously at the self-service bar, while the hygiene is poor and the sundae has a rancid smell.
