This trip, Guy's checkin' out some unique 'que. In San Antonio, a 60-year old drive-in spices up the standards like burgers and smoked brisket with Thai heat. In Denver, a Native-American joint that's mixing tradition with innovation, from grilled chicken tacos on homemade flatbread to blueberry BBQ ribs. And in St. Petersburg, Fla., a decades-old general store using the grill and smoker combo to create a Guy favorite -- Texas hash.
