 "Hell's Kitchen" is a reality television show that uses a progressive elimination format to narrow down a field of 12 to 20 aspiring chefs to a single winner over the course of one season.The U.S. version of "Hell's Kitchen" follows the same format of the UK version, although the show is aired on tape delay and not performed live, nor is there audience participation in the elimination of chefs, who are also not celebrities as they are in the UK version.The show is produced at Hell's Kitchen, a modified warehouse in Los Angeles that includes the restaurant, dual kitchen facilities and a dormitory where the chefs reside while on the show.
