Although I don't live in Tulsa, I was visiting some people who do, and they ordered a pizza and Calzone Rings from Mazzio's Italian Eatery http://www.mazzios.com/ .
I didn't actually see this restaurant, because the pizzas were picked up and brought to our house by the people who lived there, but I absolutely LOVED the Calzone Rings http://www.mazzios.com/fr_menu_calzone_ring.html .
The pizza was good, too, but after eating the Calzone Rings, I really didn't want the pizza because the Rings were so very tasty. I wish Denver had a Mazzio's. Great food!
