Guy Fieri hits the road for a Triple "P" Party! In Houston, he's checking in on a Greek diner where the machinery is as impressive as the food -- like a rotisserie spinning off-the-hook pork.

And in San Francisco, a real-deal Mexican joint is scratch-makin' it all, from the pozole to the caldo tlalpeño con pollo.
