The original pizzeria Uno is part of the chain. Go to the website (www.unos.com), order online, and select the original location (29 E. Ohio). The menu will show up with prices. Medium pizzas cost 16.99 (cheese), 18.79 (1 topping), and 20.99/22.99 for specialty pies. Add $4-5 to make it a large.
Really varies by size of the pie, for 2 people plan on $20 plus drinks.
