Moes has a pretty large menu and the prices are not too bad. I usually get the "Moo Moo Mr. Cow" which is a kid's meal but it's filling and costs less than five dollars (and includes a cookie and a drink).
I eat at Fazolis a few times a week because it is fast, reasonably prices, and the food is decent. No matter what you order, you get unlimited breadsticks.
Chipotle doesn't have a broad menu, but what they do have is GREAT. The flavor of the food is very fresh and different. The prices are reasonable and the food portions are huge.
Mellow Mushroom has a great, laid-back atmosphere. There are many different types of pizzas, calzones, and salads available (all of which are very good). The prices aren't too bad if you split a pizza with someone. Everytime I've gone to Mellow Mushroom, the service has been a little bit slow (even when it's not crowded) and the soda is always flat (get water!).
