I don't know why, but when I feel like getting Korean to go, I come to Dorca's instead of Woori Jib. It is a little more expensive than what you would find outside of Champaign, but that doesn't stop me from frequenting this place.
You get very sizeable portions. I always get their bbq chicken (bulgolgi's also very good, but I'm a white-meat eater) and it comes with a shitload of rice, side of kimchi, a few potstickers, some rice noodles... basically enough food to last me two to three meals. If you don't carry out, you get free refills on soup and rice.
Great, great food and fast service. I love this place!
