Restaurant critic Giles Coren and writer and performer Sue Perkins spend the week on the diet of a wealthy Edwardian couple. Cooking for them at home is best selling cookery writer Sophie Grigson.

Giles Coren and Sue Perkins take their relationship to the next level as they prepare for their very own royal wedding. The pair assume the roles of a modern prince and his princess-to-be as they agonise over every step of the wedding planning process, from choosing the dress to arguing over the vows. In true Supersizers fashion the programme culminates with a lavish wedding banquet featuring dishes from past royal nuptials, including everything from sturgeon a la royale to the Queen Mother's favourite eggs drumkilbo.
