Sir Terry Wogan and cabbie Mason McQueen's epic taxi journey has brought them to Britain's smallest city - Wells in Somerset. Here in the famous cathedral close, they begin their search for the region's most tempting delicacies. Cheddar cheese and sparkling cider in the medieval market place give way to Mendip wallfish cooked in fresh herbs and more cider. Locally-made cheese and cider-flavoured chorizo is a particular high point and the whole adventure ends with a banquet fit for the abbot himself.
