what to do/where to go in chelt

hi,
I hope you may be able to advise me. i@m staying in chelt with a couple of old freinds. we're in our mid 40's and hope to
go out to dinner,
have a few cocktails
have a boogie - ideally to some funk/disco/house or northern soul type music
maybe visit a place of interest

can anyone recommend anything/anywhere where we wont feel incredibly ancient and out of place - and just have a great w/end catching up.

many thanks,

GB
