Great British Menu is back, and this time the nation's top professional chefs are competing for a chance to cook 'A Feast to Say Thank You' at a glorious banquet celebrating 70 years of the NHS, one of Britain's most prized institutions. Across eight regional heats, 24 chefs compete in the toughest competition of their lives as they attempt to dazzle with their culinary skills, serving up outstanding dishes that honour the incredible work of the heroic NHS staff and give them a gastronomic experience they will never forget. In each regional heat, they first have to impress one of the surprise veteran judges whose identity won't be revealed until they walk through the door. The two highest-scoring chefs then face our exacting panel of judges - Oliver Peyton, Matthew Fort and Andi Oliver.

The two remaining London and the south east chefs must cook their four-course menus again. But will they take on board their veteran's advice as they remake their 'Feast to Say Thank You'?

The chefs need to impress the formidable judges - food writer Matthew Fort, restaurateur Oliver Peyton and broadcaster and cook Andi Oliver, as well as a guest judge from the NHS. Today they are joined by Jenny Turner who, at the age of 77, is Britain's longest-serving nurse. Both chefs raise their game and impress the judges with their inventive dishes, but only one can go through to represent London and south east England in the national finals. Show less
