Foul-mouthed and angry, chef Gordon Ramsey tries his best to help clueless restaurateurs improve their business by offering his help and wisdom gained over the years.
Despite holding Michelin stars for his cooking and creating a successful worldwide chain of restaurants, not everyone takes to his advice.
His ideas usually involve the creation of a new menu for food that people want to eat and revamping the dining area. In some cases new ovens and fridges are provided.
Some of the people he tries to help simply will not be told, which ignites the fiery chef's temper with a typical outburst being largely bleeped out for broadcast.
Over the years, Gordon Ramsey has managed to turn around some poorly-performing restaurants and save their owners from going bust.
On the way he has cooked-up moments of television gold – Gordon being poisoned by a young chef who served up undercooked and out-of-date scallops being one memorable moment.
So successful has this Channel 4 programme been that the format was successfully exported to America where Gordon's inimitable style was let loose on American restaurateurs.
This version, Ramsay's Kitchen Nightmares USA, is also just as shocking as its British counterpart.
The repeats of Ramsay's Kitchen Nightmares remain popular as do the shows in which he revisits the original restaurants – the ones which have listened to him and not gone out of business, that is.
Those restaurants which struggle tend to be those with owners and staff stuck in their ways with a reliance on prepared or ready-made meals – which Gordon hates to see.
Ramsay's Kitchen Nightmares has not just featured dire restaurants in need of help in the UK but also in Europe too, particularly in Spain's Costa del Sol.
For most the heat is on when Gordon turns up to dish out his advice and it makes for interesting TV watching.
Ramsay's Kitchen Nightmares is shown on Channel 4 with some repeats available on the channel's on-demand video service, 4oD.
