Junguk is a small Chinese restaurant in Seoul that serves jjajangmyeon, jjamppong, and tangsuyuk. Its thin jjajangmyeon noodles are made in-house, absorb the sauce well, and are not heavily salted, while the jjamppong broth is clear. It is open only from 10 AM to 1 PM, Monday through Saturday, and closes early when ingredients run out, so a wait forms even in the morning. Portions are on the small side.
