Tried about 10 different slices of pie, including Lombardi's, Grimaldi's, and several others. Also hit Les Halles & Mesa Grill, both excellent.
However, the best bite of food I had all week was a Gyro from one of the 10K 'Halal' Food carts scattered across Manhattan, which are almost as pravelant as hot dog carts it seemed.
What set it apart from Gyros around here is that in addition to the standard Tzatziki Sauce they put on them, they also put a slightly thick blazing red sauce on there as well. The sauces mix amazingly well, and it gives it a spicy kick that just puts it over the top. Seemed standard up there, we had 3 at different spots around town, and they all did it the same way.
Anywhere around here that offers the Hot Red Sauce to go along w/ the Z-sauce? I'd kill to have another...

Oh, and despite Lombardi's/Grimaldi's both being near perfect versions of Coal-fired pizza, it gave me even more appreciation for how good Coal's in Louisville is. They can't match the NYC ambience obviously, but as far as the pizza goes, it's really not far off, if at all.
