Hands-down my favorite all-you-can-eat pizza place. Not only is the pizza delicious but they have a great salad bar and even a pasta bar!
The salad bar is clean, well stocked, and has a great selection of toppings and dressings (my wife was a big fan). The pasta bar (which I think is a great addition to the standard pizza and salad restaurant) is delicious and has a nice selection of different fresh pastas and sauces (pro tip: get some of the marinara to go with your cheese bread, it's awesome).
Now to the pizza. Normally I stay away from all-you-can-eat pizza places because they trade quality for quantity. This place has both. The quality of the pizza here is comparable with any take out or sit-down pizza place in the east valley that I have tried. Not only is the pizza high quality but there is a huge selection of creative combinations. They even have dessert pizzas and new flavors every month! At PPC they go way beyond the standard flavors. My favorites were the pesto chicken and the chicken bacon ranch while my wife loved the Hillbilly and the BBQ chicken. I also love the fact that you can get cheese sticks in the pizza buffet as well.
In addition to the food we found the customer service to be friendly and attentive and the atmosphere to be comfortable and inviting. They have everything from big tables to intimate booths.
I have already recommended this place to multiple of my friends and will be returning soon!
