We love Primos Pizza.  It is very affordable and the pizza is actually good!  It's an all-you-can-eat style restaurant and the staff is very polite and courtious.  They will even make you a specific pizza and bring a plate of it to your table.  The dessert pizzas are to die for, especially the chocolate chip cookie pizza.  
Primos gets two thumbs up in my book!
