Folks from various not-as-cultured parts of the country would probably "steer" you (forgive the pun) on what places they visited in NYC that "had a good burger."
A little advice -- while NYC has some of the best steak houses and burger joints in the world, you don't go to NYC to have a burger! I'd suggest to anyone visiting NYC to take the opportunity to break out of the uncultured American mold, and have yourself some truly worldly cuisine. NYC offers cuisine from around the world, all in one place. Italian, German, Indian, Greek, Mediterranean, African, etc.
For those that think the Barilla pasta with Ragu sauce is "Italian," you'll have an awakening when you come to NYC!
