If your budget is conservative, but you want a decent meal...Tower Bistro is your spot. Sort of a cafeteria feel, but not too terrible.
I had the buffalo chicken salad, which was great. The regular size take out box of salad...$5.74! Talk about good AND cheap. Of course they had more options like a huge slice of pizza for $3.
Aside from the cafeteria feel, I was pleased with the cost and the food. I'll definitely go back!
