I really like Pizza Etc., though maybe that's partly because it's practically right next door to my house ... Anyway, they inexpensive offerings: pizza, calzones, and subs, the typical things you can get from a pizza joint. In my opinion their chicken salad is amazing.
Sometimes the wait for food is a little long, but I consider that a better alternative than pre-made stuff. They also deliver and accept orders to be picked up, so that can cut down on the time you spend waiting there. If you do wait or eat there it's usually very clean so there are no problems.
