I was looking through my bookmarked websites searching for something, when I (re)found this one: http://amiinvisible.com/

The idea of it is that if you find an especially disabled-friendly business or service, you recommend it for inclusion on this site. Not much on it at the moment, but perhaps they have not been able to give it the publicity it needs yet - we could help a bit by offering recommendations and by 'spreading the word'.
