Veggie Pizza from Costco

While not strictly a sit-down restaurant, if you're on the north side of town and have a Costco membership, here a good deal for feeding you and several friends. While it's not on their menu, the food court at the North Austin location sells a 18" vegetarian pizza for $10. It has cheese, tomato sauce, green peppers, onions, mushrooms, and black olives. You can call their pizza order line at 512-634-2257 and pick it up in about ten minutes. I've also had good success picking up one of these and then dressing it up with veggie pepperoni and recooking it in the oven.
