After their crazy Californian summer, Matilda and the Ramsay bunch are back in Britain and Tilly is getting ready to cook a very special meal for dad Gordon's 50th birthday. Starting his birthday with a bang, Tilly, her sisters Megan and Holly and brother Jack decide to hide the invitation to a secret birthday party. Tilly and Jack are going to become fine-dining chefs for the party, cooking up a three-course menu to rival the best restaurant, including a starter of salmon and prawn ravioli, main of fillet of beef and a very dramatic dessert! Let's hope the birthday boy enjoys it as much as Tilly enjoyed making it!
