Jungguksung is a Chinese restaurant in Ulsan run by an overseas Chinese family, serving set-course Chinese meals and handmade dumplings. The gunmandu are filled densely enough to release juice when bitten, and the chili shrimp is made by deep-frying a whole shrimp with the head still attached and adding sauce on top. There is a room that seats more than 10 people, and warm tea is served so guests can drink while waiting. Even on weekdays a wait forms, so walking in without a reservation means waiting.
