KTO highlights jjajangmyeon as an Incheon regional food. This Korean-Chinese noodle dish mixes noodles with a dark chunjang-based sauce; toppings and sauce recipes vary across restaurants.

Before ordering: Check whether the sauce contains meat or seafood, whether single portions are available, and current menu prices and extra-portion options. No particular restaurant is verified as the original or currently open.

This is an evergreen guide to choosing regional food, not a restaurant ranking. Individual restaurant hours, closures, menus, prices and booking availability were not verified; check the venue directly before visiting.
