I could say drive in and drive straight out.
Exeter Cathedral is rather beautiful....
For a pub, 6 miles out to the SW, there is the Nobody Inn at Doddiscoombeleigh.....not as good as it used to be as ti was exceptional but still worth visiting

I would also consider Bovey Tracey (the Arts and Contemporary Crafts Centre is wonderful)

And Dartington is not that far away.

Plus you have all the beauty of Dartmoor and the countryside - get off the main roads....Widdecombe etc...
