From the DVD commentary, episode 1:
Crowley and Aziraphale are leaving the St. James’s Park
Douglas Mackinnon: Here we have a Sherlock easter egg that nobody has got as we speak. Do you even know the Sherlock easter egg that we have here?
Neil Gaiman: I believe it’s the Diogenes Club…?
Douglas Mackinnon: Yeah, it’s the exterior of the Diogenes club, which is just about to appear and - just there. That is the Diogenes Club where Sherlock and Watson go to visit Mycroft. And I had a plan that I never quite got to. I was gonna have them walk in their Victorian costumes, walk into the club in the background, you know, doubles of Benedict and Martin. But we never quite got there.
