Well this was farcical, imo, and without trying to be cruel. It was a whole lot of parts of a whole lot of pizzas more or less strewn on tables running down 5th. The tables broke completely for the cross streets, so it wasn't continuous. Where I saw it, it wasn't a pizza but rather individual pieces adjacent to each other in alternating fashion, creating a pizza piece line down the middle of the table. MOst of the pizza I saw was from Domino's in their boxes, opened up, and many people were walking away with a small stack of those boxes. I couldn't see much connection to Italy (other than that it was pizza) or much promotional value in it for the various sponsors (other than that they did put up their banners for a while on 5th where they normally wouldn't have been). And it's hard to imagine that this would impress anyone at Guinness.
It was nice to have a free slice or two of pizza, however!
