I have on numerous occasions and it is right up there with Chicago and Buffalo pizza, but certainly not better.
I thought the comment about "cardboard crust" was particularly silly - all the good places in NYC (and there are thousands) make their own dough, and while the crust is not as thick as Buffalo or Chicago style, it is much thicker than the New Haven/lower New England style of pizza.
It is even sillier for a Chicagoan to say it, because there are plenty of places in Chicago that serve an ultrathin crust pizza - cut into squares because the crust is so thin and hard you can't fold it like a New York slice.
