The country's top chefs are competing to cook at a fabulous banquet to celebrate the very best local produce from across the land and the pressure is on, as the host will be HRH The Prince of Wales. Each week three chefs battle it out in the kitchen for a chance to cook at the banquet, and this week it's the turn of the chefs from the North West - Johnnie Mountain, Lisa Allen and Aiden Byrne. Only two chefs can make it through to cook for the Great British Menu judges at the end of the week and one will be going home. That decision lies with former champion Marcus Wareing, who will scrutinise their dishes every day. Today it's the fish course. Will the winning dish be Gloucester Old Spot pork with smoked venison, salt marsh lamb with sweetbreads, or oak roast middle white pork with broad beans?
