Aside from the obvious things.
SWMBO and I will be in NYC for 6 days in July/August. I have some meetings with clients and agents but I am sure that there will be time for a bit of sight seeing and since I have never been there (unless you count Newark airport at 3am once!) and neither has t'wife, I thought I would ask and see if any of the well travelled Geeks had any 'off piste' suggestions for things to see, do, buy or eat!
As a photographer, I will of course be worshipping with my MasterCard at the Holy Grail that is B&H. Apart from that.....
