Judging by the percentage of Korean customers, it must be the most authentic Korean place in Champaign, and it's better Korean food than I expected to find in such a small town.  A-OK - three stars - seems about right.  The food was a little bland, but the flavors were generally right and cooked well.  The ingredients seemed lower-quality as compared to Korean places in larger cities, but still very edible.  If I had a jones for Korean food while in Champaign, I'd go here without hesitation.  If I just wanted some good food, I don't know that it would cross my mind while in Champaign, though.
