After almost 10 years and over 300 battles, many professional chefs from all around the world have appeared on the show. Many have gone on to create their own restaurants or even chains of restaurants based on their success. As it was once said on the show, a challenger who loses on Iron Chef can expect full bookings at their restaurant for a year, while a challenger who wins can expect full bookings for three years. Below is a list of countries that have restaurants owned and/or operated by either an Iron Chef or a challenger chef from the show.
