A recent Intel study that ranked towns in the U.K. by the number of hot spots per capita, noticed that more hot spots in the U.K. are in pubs than anywhere else: That's certainly a big difference from the U.S. where cafes make up the largest group of hot spots. (As opposed to pub-based "hot sots," which are overheated regulars.)
The Intel study ranked Exeter number one, followed by Bangor in Wales and then Newcastle. London ranked 33 because even though it has the most hot spots in the U.K.--and the second most in the world behind New York--its large population puts it lower on the per capita-based listing.
