Heaven is a place where you can get a hot, fresh slice of thin crust with lots of fresh toppings (i.e., there’s more toppings than dough), the crust doesn’t sag/droop and there is a wonderful cruch when you bit into the slice. Dominos, like most chains, would not fit in that category. Personally, I won’t eat the doughy, saggy crap that comes out of most pizza places.
There’s a chain I’ve lately grown to like which fits your criteria: modpizza.com
I also like Bertucci’s.
