I knew someone from Chicago would respond!
My wife has had Uno's pizza. She enjoyed it very much, but still favors our "thin crust" pizza, dripping with oil and loaded with cheese and pepperoni.
El Yummo!
I lived in Florida but, as much as they try, they can't get the NY-style pizza down pat. They use the exact same ingredients, but blame the water.
Do they use the very same tomatoes and cheese? Those ingredients are key. If it's the water, perhaps they should try bottled water! I tried an Uno's pizza in Boston and it was a HUGE disappointment. Not even close to Chicago style. Not even close.
