Papa johns no doubt, dominos is a ****ing rip off.
Greasy, spongy base, poor toppings, slow delivery drivers, the tomato base has a really bitter taste. Papa Johns is miles ahead.
Unless I'm out of town though I use an independant joint, chains are overpriced and nowhere near as good.
My local uses a real woodfired oven, all the toppings are good quality, the tomato sauce is home made, really friendly.
