Papa John's is by far the best of the many pizza chains in the US(Pizza Hut, Little Cesar's, Domino's, etc.)! Their pizza is delicious and always seemed a bit pricy (for good reasons) to me. They are starting to compete more with pricing, the 1 topping large pizza is a great deal!
Pros: GREAT PIZZA, implementing new deals, GARLIC SAUCE
Cons: Price (though getting better), lack of dine-in
