Goseokhwan Son Mandu Main Branch is near Hansung University Station and sells hand-made dumplings. The main dish is mandu jeongol, and the shop also serves mandu gukbap and gun mandu. The gun mandu is crisp, and the dumplings in the mandu gukbap keep their juices. It sits in a remote alley in Samseon-dong, so it is hard to find on a first visit.
