Ahh, but chain store pizza which is normally very wrong can occassionally be oh-so-right. You have to be in the right frame of mind for the greasy soggy muck - but when you are: yum!
inappropriate toppings
One of the best pizzas I ever had had a tomato base and cheese on top, with prawns/shrimp and banana in the middle. And, not - that wasn't a late night drunken concoction, but ordered from the menu at a long-established place.
