I'd seen several recommendations for Sal's, here and elsewhere, so decided to give it a try.
I was pretty sure I had made a good choice as soon as we got there. It was in the middle of a really hard thunderstorm, but the line stretched out the door, with many more customers squeezing in to pick up to-go orders that had been phoned in.
Most of the people in line were just ordering a slice, but there were three of us and we were hungry, so we ordered a whole pepperioni pizza. They offer only one size: huge (18 inches, I think). It was as good as it was large, although anyone wanting to quibble might note that it was more than slightly greasy.
The thick Sicilian pizza seemed to be a popular choice, but we went with the traditional New York thin crust.
Sal's is obviously the choice of the locals. There are four or five other pizzarias within a block or two. None of the others had more than a handful of customers as nearly as I could tell.
