Whenever my family and I are looking for dine in or take-home pizza, we think of Nick-N-Willy's on 7th St/Thunderbird. Their selection of unique pizzas is excellent, and they always have daily specials. This restaurant specializes in take-and-bake pizzas, which means you take a freshly-made pizza home and bake it yourself. However, they will bake pizzas for you if you're dining in or if you just don't want to do it yourself. Keep in mind that many of the specials are for take-and-bake only.
My family of 3 can typically eat (salad, pizza, and cookie) here for under $20. We especially like to go on Sundays, as they offer an all-you-can-eat salad & pizza special.
The service has been top-notch for us. The cooks/cashiers have always been pleasant and helpful.
If you like spicy food, try the Fresh Jalapeno Burn. If you are in the mood for something different, we would suggest the Mediterranean. And don't forget the take-and-bake cookie for dessert!
