I was actually in Delhi last year for a holiday, or rather in Rajhastan but passing through Delhi on the way back from the Taj Mahal.
Some of the middle class Delhi guys here have been sharing their experiences of Delhi changing in the 21 century, particulary with respect to their arranged marriages, divorce and the sexual freedom of the west.
Culturally speaking, India with its thousands of years of history, things seemed to have changed more in the past five years than the previous 3000. There is no evidence of any gay bars in downtown Delhi, not that hangin about in bars in a predominantly Hindu society, is the thing to do. However the adoption of interest in the world cup and of all things current in the US, leads me to suspect the first "Stonewall" isnt that far away.
Downtown Noida has a mega plex showing English language (ie US) movies, TGIFs, Ruby Tuesdays and half a dozen restaurants which look familiar from my last trip the US.
At 42 degress I dont thing there will be a 'leather' bar like Manacle here for quite a while yet though
