Their knives are getting sharpened – again – as Top Chef goes EXTREME! The new head-to-head format pits Cheftestants from past seasons against one another in three rounds of extreme culinary challenges. The winners of each of these battles will compete against each other in the season finale – a definitive battle royale of pure gastronomic talent and ambition. In the end, old rivalries will be settled and one chef will cut down the competition to win the grand prize and, more importantly – ultimate culinary bragging rights.
