So far Gordon has found his best Italian, Indian, French and Chinese restaurants and in tonight’s programme, Gordon and his team travel around Britain looking for brilliant local Spanish restaurants before inviting the best two to cook in the F Word restaurant.El Gato Negro from Yorkshire and Lola Rojo from London face one of the biggest challenges of their lives as they prepare a three course meal under Gordon's watchful eye - including prawns, sea bass, fish stew and churros with chocolate.But who will be good enough to wow the 50 F Word diners and go on to fight for the title of The F Word's Best Local Restaurant ?Meanwhile, Gordon travels to Spain to hunt for an extraordinary delicacy - Percebes or Goose Barnacles - that is both dangerous and difficult to source.And Kelly Brook takes Gordon on in the Recipe Challenge with her recipe for stuffed peppers.
