Adored by the Network: If you were to turn on Food Network right now, chances are you will be watching this show. Not only has it come to dominate Food Network's prime time schedule, but it's spawned a number of spiritual spin-offs including Cutthroat Kitchen and even Chopped: Canada. Even Guy Fieri, who dominates most of whatever evening airtime isn't taken up by Chopped with Diners Driveins And Dives, now has his own Chopped-style show, Guy's Grocery Games.
On season 8 of Series/Food Network Star Giada's team visited Arthur Avenue (the original Little Italy) and Arthur Avenue Trattoria and Mike's Deli. The chef/owner competed in the Cornish hen episode.
Speaking of Food Network Star, Michele Ragussis once competed on Chopped.
Michael Gilletto is one odd case. As The Other Wiki notes, he appears on Restaurant: Impossible as one of the four chefs to become the head chef. He initially wins, but it was clear he was having second thoughts and did not take the job after all. Later, when Food Network aired a short home-cooked version (aptly named "The Chopped Open Your Basket Challenge'', essentially a promo advertisement), he's one of the judges.
What Could Have Been: Ted Allen humorously remarked that Chopped was going to take place in an eccentric millionaire's mansion with the losing dish in each round going to the chihuahua. It was too much for Food Network.
