Well, funnily enough there is an American diner in Swadlincote! It is one of those metal/aluminum (spelled the correct way!) dining cars with a 50's theme - super cute!
It would be hilarious to have a group of Americans rock up to the joint... it's run by British people, ironically - lol.
Yeah, Tamworth is just off the M/A42, so it's directly connected to Birmingham and Nottingham (kinda sits snuggly between the two on the motorway!)
