My friends and I differentiate between our two favourite Chinese places in C-U: The "really good one" (Lai Lai) and "the really fast one" (Empire). Lai Lai is a bit spartan in its set up, but if you want a great selection, central location, and a delicious menu, hit it up. I think it's ideal for a lunch time meet up with people from the university, and the tea dispenser is rather convenient.
Enjoy.
