The first pizza place in my neighborhood - and my introduction to pizza as a kid - was a family-run carryout, and the pizza was always rectangular. I’ve never had such a good pizza since, but I don’t think it was the shape ;-)
They made great meatballs, too.
we have a couple local pizza joints that do a good job...
but for a major brand... we think Round Table is still the best pizzas (very expensive nowadays, really NOT worth it.... tho you can usually get a couple dineros discount by checking at their website for coupons)
