Mandarin Wok was one of the few affordable and authentic Chinese restaurants on the U of I campus.
The regular dinner menu is huge and the food is good. Dishes come out with pretty decent portions. My friends and I have often claimed Mandarin Wok as our official birthday dinner place. There are several tables meant for big groups and for college kids, we were never disappointed.
In addition, the clutch thing about this place is definitely the fact they they served dim sum. To me, that's always a win.
