This trip Guy's rolling out for something new from the grill - and more. In San Antonio, Texas, a 60-year-old drive-in where the owners are putting a Thai twist on classic Texas bar-b-que. In Denver, a Native American joint turning folks on to grilled, braised bison ribs topped with blueberry sauce. And in St. Petersburg, Florida, an old-school sundry shop and restaurant smoking chicken for their own Texas hash.
