Our guest chef has to create and cook a full dinner menu in a real restaurant. The diners are real diners, and among them each week is a critics table with three top food critics ready to give an instant verdict and a star rating from one to five. The resident critics are Tom Doorley and Paolo Tullio, with one other guest critic each week.

The celebrities who become chefs for a night are people who have a secret passion (and, sometimes a real talent) for cooking. Now they have the opportunity to "go pro" for one night and serve up a real restaurant meal. But they won't be all on their own. They will get expert advice - and the highly trained regular staff of "The Restaurant" will work with them at all times - even when they don't agree with the approach and ideas of the new chef.
