Jeilgopchang is an old gopchang restaurant near Changdong Station in Seoul that serves sogopchang jeongol and modum gopchang gui. The signature gopchang jeongol boils vegetables such as crown daisy, chives, and onion with jjolmyeon noodles and tteoksari rice cakes, and the broth is clean. A small jeongol is enough for three people, and fried rice can be added at the end. Beef offal makes up more of the dish than gopchang, so it eats like a naejang jeongol.
