Where should I go in London for great blues with good restaurant?

I am looking to dine in a restaurant where great blues/ latenight jazz plays and maybe... some dancing? ...

Ronnie Scotts........

Hmmm, dont know. I know London is a great place.

Well, Django Reinhardt did some blues, and this guy does some Django. But it's mostly jazz. I've never been, but I stumbled across this video in youtube, and it is amazing.
Can't vouch for the food or the place though. This video was from March 2006 at a place called "Quecumbar".
