One of Charleston's legendary locals, Bill Murry, is taking on food and entertainment mogul, Guy Fieri, in a nacho-building contest. "Nacho Average Showdown" will stream LIVE on the Food Network's Facebook page on Friday, May 15 at 5:00PM EST. The live showdown will raise money for Guy Fieri's Restaurant Employee Relief Fund. Each superstar will be joined by one of their sons, who are also restauranteurs, Hunter Fieri and Homer Murray. Their sons will help them tackle the task of building some glorious nachos. The competition will be hosted by chef Carla Hall, and judged by Terry Crews and Shaquille O'Neal.
