My favorite Chinese place!
It's right by the Rosati's on Arlington Heights and 83.
It's near my work so I get the lunch special a lot (which has gone up recently). I think it's at about $7. But they give you two lunches worth of food, and it is SO delicious. I always get the Mongolian beef with fried rice. It comes with an egg roll and all three of these things are beyond delicious.
Dang is the owner (I think) and he is incredibly friendly. Go there more than once and he will remember you. Whenever my coworkers or I go there, he asks after the other person.
Really reasonable prices and beyond-great food. Especially when it was JUST made. Very hot and fresh :D :D Highly recommend.
