This week Gordon takes a sentimental journey back to Paris, the place where he spent his formative years as a chef. But in the city that is a gourmet's dream, he's about to encounter one of his worst ever Kitchen Nightmares. Three years ago, feisty Scot Rachel made the jump from waitress to restaurateur and, together with best friend Stephanie, bought Piccolo Teatro, a bijou vegetarian restaurant in Paris on a mission to convert the carnivorous French into a nation of vegetarians. But handicapped by her total lack of experience, she is struggling to keep the restaurant afloat. She can't motivate her staff, she doesn't bother opening for lunch and the punters are totally turned off by the awful rabbit food she's dishing up. As a result, Piccolo Teatro is losing £5,500 a month. Will Gordon be able to perform an eleventh-hour miracle, or is he about to admit defeat?
