Scott Wiener knows a thing or two or three or four about pizza. He offers guided tours of different pizzerias in New York City, but that's not all. He also is a writer & columnist for Pizza Today magazine and holds the world record for owning the most pizza boxes. We talked with Scott about the tour, what makes a good pizza and the history of the most wonderful food group ever. For more information on Scott's tours & classes, check out his website, and for more information about his charity dedicated to helping feed front-line health care workers, check out the Slice Out Hunger website.
