In the time since I sadly had to give NYPD pizza a single star for not having any gluten-free products available upon my visit, I've been twice more. Both times, as on my first visit, the food and service were outstanding.
I was also contacted by two members of management who were very apologetic about running out of GF items and who offered me a gift certificate for the inconvenience. I didn't accept it because I wanted my follow-up review to be untainted by the spectre of paid advertisement, but it was very nice of them to offer.
