Ramsay's Kitchen Nightmares

In each episode, 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.
