Jangin Haejangguk is a Korean restaurant in the alley by the main gate of Pusan National University in Busan, serving ppyeodagwi haejangguk. The signature ppyeodagwi haejangguk comes with warm, clean-tasting broth and well-cooked meat. Arriving even a little late at lunchtime brings a wait, and a machine serves the food. The menu is simple and easy to understand.
