Today only, at Uno Pizzeria & Grill, buy one pizza and get a second pizza of equal or lesser value for $5 in celebration of National Pizza Day. (Deal applies to takeout orders only.) That's a savings of at least $5 -- it's a much bigger savings if you want something besides a small, mostly topping-free pizza, and who can say no to a Chicago-style deep-dish pie from the guys who (allegedly) invented it in the first place?
