Overview: Louie Mueller Barbecue (Taylor, Tex.) • Forte European Tapas Bar & Bistro (Las Vegas, Nev.) • The Highlander Diner (Atlanta, Ga.) Guy Fieri's trip is all about the three B's: beef, barbecue and bar food. First, he stops in Taylor, Texas, at one of the first DDD barbecue joints to pay homage to an old friend whose son is carrying on his legacy. Then, it's on to Las Vegas, where Bulgarian bites and the ultimate Triple D prank reigned supreme. Finally, in Atlanta, a punk rock bar is still flippin' the script on bar food.
