The Manhattan Users Guide (MUG) has been a great resource for NYC since the days it was Quarked-up, printed, and distributed to in-the-know subscribers(who then photocopied it and passed it on.)
For the past couple of years it’s been a (free) email newsletter and web site.
Today, it’s got some playful data:
