Pizza Cones aren't new (Adam covered them here over 2 years ago), but they are newly abuzz. There must have been a strong pizza cone presence at the Las Vegas Pizza Expo last week, or enough to have RyanSeacrest.com (yes, that exists) asking if they're the next big thing.
Just looking at them kind of makes me feel like I swallowed a boulder, but that doesn't mean I don't see the appeal. There's a definite fair food effect, and who can say no to that?! Sure, you might regret it later, but would you at least give it try?
