My inlaws live in Bristol and traffic there IS a nightmare, but outside of Bristol should be fine. It's their terrible traffic planning inside the city that's bad.
How about Cribbs Causeway? It's just off Junction 17 of the M5, so you don't have to go into the city centre, and there are several restaurants in the complex area (plus it's only 20 minutes drive from my parents' house).
I'll be in Leicester! Let me know if you guys are ever near there
Also love any excuse for more day/weekend trips 
I live in Lincoln, which is only about an hour from Leicester

I know a woman here who is a Brit but moved to the USA like, in 1970. She's now in her 60's and she's been in the US longer than the UK and is a dual citizen. Unfortunately, she's lost a lot of her accent. I don't mind developing a British accent and losing this one though 
My aunt moved from the UK to the US in 1978 - she only intended to live there for 1 year (they were advertising for British nurses to work in the US), but she's been there ever since! She became a US citizen in 2001 and has now lived in the US for 14 years longer than she lived in the UK. She hasn't really lost her accent though, as she has lived with a fellow Brit for the entire time... their accents have changed a little, but they still sound mostly British (they have a bit of an Australian-sounding, transatlantic accent). In comparison, one of their friends married an American and ended up living in a small, rural town in the Deep South, and when I met her, I had no idea she was British and originally from Devon, because she had a full-on Southern US accent
