This trip, Guy Fieri is grabbing grub cooked up with some great gear. In San Francisco, a place firin' up lights-out lamb and huge pork biscuits in some of the city's last remaining indoor smokers. In Stockton, Calif., a multi-generational Italian deli making ravioli on an amazing century-old machine. And in Maui, Hawaii, a mobile pizza oven puttin' out island twists on meaty pies.
