The Roman city of Bath is the destination for Sir Terry Wogan and cabbie Mason McQueen who are seeking out the finest delicacies that over 2,000 years of history can produce. From Bath chaps to beetroot sorbet they see and taste it all - not forgetting the honey-glazed dormice, cooked in the roman style. A reviving brew served by the UK's reigning king of the baristas sets them up for a visit to the catacombs, where an eco food initiative is making mushrooms out of waste cardboard and coffee grounds.
