The best of all the pizza chains.
I have a confession to make, I just recently started actually getting into pizza. Before I reached 16, the only pizzas I ever ate were from chains, restaurants/buffets that don't specialize in it and frozen.
Although I am seeking to expand my pizza horizons, I still love my Papa John's. I haven't had it in a while though, money is tight, Pizza Hut has that $10 deal and a Little Caesars is practically next door to where I live.(I love pizza regardless, but still...) The sauce is always bursting with flavor, the toppings are awesome(I love their Italian meat pizzas so much) and they ALWAYS give you garlic sauce. Also, the breadsticks are to die for.
I may become a total pizza snob one day, but I'll never have too sophisticated a palate to enjoy a slice from Papa John's.
