JB Gill hits the road in search of the ultimate motorway pitstop, uncovering the weird and wonderful world of the UK's most notable service stations and revealing which one the public has crowned best in a Which? poll. Along the way he explores Britain's busiest, newest and oldest service stations, travels to the Lake District to find out what the farm shop fuss is all about, and races against the clock to see if it's possible to grab a coffee and head to the loo in under five minutes.
