Good Indian around Soho
I'm not sure if Hampton Chutney delivers, but they're not far from there. Not the most authentic Indian I've ever tasted, but considering the location it's as good as it gets.
Brick Lane (on 6th street in the East Village) might also deliver to your office. Though, again, it's more of a British/American style Indian than what's typically on offer in places like Jackson Heights or Lexington Ave in the 20's/30's.
