When I came into this thread I immediately did a search for Prince knowing there would be a comment about it here.
I do like their slices but I am not leaving mid-town for that. I perfectly enjoy Upside Pizza slices.
Prince st pizza is a joke, it's literally just a pepperoni gimmick and any serious NY'er isn't putting up with that crap, let alone waiting on a stupidly long line to eat it.
I tried it because I worked around there and it was before it went viral. There's no need to travel across the city to try a "slice". When I'm in a neighborhood that has a good spot, I'll stop through. There's nothing about Prince st that requires it being tried unless you want to participate in the trend. It's just a basic pizza place that went viral because they put a stupid amount of cupping pepperoni on their slices. It's really got nothing to do with what I'd call my conception or experience of pizza as a lifelong New Yorker.
