Gordon's off to The Priory, but not to rub shoulders with wayward actors and musicians. This priory is a huge, 100 seater carvery in Haywards Heath, Sussex.

This unusual venue was once a place of meditation and tranquillity as the chapel of a nineteenth-century convent. It's in a beautiful location and has been offering bargain roast dinners to it's regulars for twenty years. But under its current management, things are in need of divine intervention.

Owner Scott, an ex IT consultant, bought the place for £300k but with an ageing clientele eating for half-price, he’s now losing a massive £5,000 a week.

And despite the heavenly setting, the food is straight from hell: recycled meat, soup in a bucket, synthetic sauces and to make matters worse, a lazy head chef content to preside over food-encrusted ovens and a disaffected staff.

In one of his toughest tasks ever, Gordon’s got to move mountains to turn a time warp into a trend-setter. He'll be dishing out penance, making Scott repent for his business sins, get the staff to confess their faults and above all transform The Priory’s turgid food into ambrosia. Will he inspire a miracle, or witness a disaster?
