Guy Fieri's having a sandwich extravaganza! First, a lunch spot in Indianapolis is serving up serious flavors with the-bomb brisket au jus and rockin' roast pork. Then in San Luis Obispo, Calif., a next-level burger joint is plating killer barbacoa and a legit tri-tip dip. Plus, a San Antonio brewpub is scratch making a sourdough Rueben and puttin' out pastrami pizza with a punch.
