I just got back from 3 weeks in B'lore, and found absolutely nothing gay about the city. Sorry.
Remember that homosexuality is still illegal in India, although delhi just got its first gay bar. Culturally, we're virtually nowhere in that country. I don't mean that there's open hatred, there's just virtually no understanding that such a thing as homosexuality exists!
What are you headed out there for? You can email me for any discussions about doing business out there.
BTW, nothing gay about it, but I cannot recommend the Leela Palace highly enough. Easily the nicest 5* hotel I've ever stayed at.
