Restaurant Critic Giles Coren and writer and performer Sue Perkins spend a week on a diet spanning the Regency Years of 1789 - 1821. With the wonderful Rosemary Shrager cooking for them at their country manor house, they enjoy the full trappings of the landed gentry. Dressing as a Jane Austen heroine, Sue is on a mission to find a husband, while Giles indulges in being a dandy.During their week they try a meal fit for a Prince with boars head and salmon poached in Champagne. Giles tries the roast beef of England and together they discover the origins of the sandwich while gambling away their inheritance at the gaming tables. A week filled with drunken abandon and Giles in debtors prison, the Supersizers end their eating extravaganza in true Regency style with a ball complete with dancing.
