Sunsimwon is a Chinese restaurant in Yeosu that serves seafood jjajang on a hot plate, samseon jjamppong, and tangsuyuk. The seafood hot-plate jjajang is defined by its wok fire flavor and the seasoning pressed onto the plate, and the tangsuyuk arrives with a ketchup-based sauce poured over it. A wait forms around 11 a.m., and CatchTable remote queuing opens at noon, with on-site registration only before that. The portion of noodles in the hot-plate jjajang is on the small side.
