Guy Fieri is circling the globe starting in Salt Lake City where a Vietnamese sandwich shop has exploded with six -- count 'em -- SIX locations around town. In San Antonio, Texas, a Greek chef is whippin' up real-deal Mexican for breakfast, lunch and dinner. Finally, a haus in Glendale, Arizona, that hasn't missed a beat in their quest for true German flavor.

It's all about the beef on this trip as Guy Fieri pops into a classic diner in Marietta, Georgia, for a taste of what's topping the charts these days. Next, it's on to San Antonio where a carwash-laundromat-kitchen combo is crankin' out killer burgers. And in Gilbert, Arizona, there's a joint pullin' all their ingredients from their own backyard and giving new meaning to the phrase, "farm to table."
