There is a fair amount of action supposedly taking place inside a bar. I can't remember which one it is (and I don't think it really matters) but at least I can confirm that these are genuine bars that were once situated along Hanoi Road in Tsim Sha Tsui.
We can see signs for the Fairyland Restaurant and Bar and also the May Flower next door. On the left hand side of the screen you can see the partial sign for Kam Lung Co tailors which has featured a few times on the blog before (most notably as one of the shops that can be seen in The Man with the Golden Gun opposite the Bottoms Up club.
Anyway, Doug has a bar card on his FLICKR stream for the May Flower which puts its location at #20 Hanoi Road. But sadly that whole side of the road was razed and replaced by the monstrous K11 development.
