Leicestershire Aero Club has a good reputation for the social club environment. There are lots of pilots at all stages of training and lots of "buddy" groups form amongst the newer pilots.
Thursday night is themed night, usually curry but sometimes something different. Tuesday night used to be ground school night. I'm not sure if it still is, but there's still a social gathering on Tuesdays. Weekends there are almost always plenty of people around, particularly over lunchtimes, unless the weather is completely diabolical.
PM me if you think you might want to visit and I'll arrange to meet up with you, if you'd like to.
