While non vegetarians enjoy their food as well, I find Pockets to be a great option for vegetarians looking to eat out. The pockets are cheap, delicious, and because meat is optional you won't pay for something that you won't eat. The Greek Pocket is really good, with delicious dressing on a greek salad stuffed inside their warm baked bread. The Southwest is also really good, for those looking for an American taste. Their delivery can be a little slow, but they make sure to make your food right. And their employees are very friendly, both in delivery and eating in. All in all, Pockets is a great option if you want great, cheap food that's actually healthy.
Pros: Cheap, healthy, delicious
Cons: Sometimes slow delivery
