백종원의 미스터리 키친

Ramsay visits a failing restaurant and acts as a troubleshooter to help improve the establishment in just one week. Ramsay revisits the restaurant a few months later to see how business has fared in his absence. Episodes from series one and two have been re-edited with additional new material as Ramsay's Kitchen Nightmares Revisited; they featured Ramsay checking up on restaurants a year or more after he attended to them.

Aspiring restaurateurs brave Ramsay and his fiery command of the kitchen as he puts the competitors through an intense culinary academy to prove they possess the right combination of ingredients to win a life-changing grand prize.

Amateur chefs compete against each other by hosting a dinner party for the other contestants. Each competitor then rates the host's performance with the winner winning a £1,000 cash prize. An element of comedy is added to the show through comedian Dave Lamb, who provides a dry and "bitingly sarcastic" narration.
