NYPD is an excellent small chain. Top notch pizza sauce flavor, excellent crust and lots of cheesy goodness. Their sausage topping is one of the best available anywhere. Their cheese knots are also very good. The pricing is higher than many NY styled pizzeria joints, but the consistency of flavor and excellent results each time keep me coming back.
I've never come to NYPD and been disappointed in the taste or temperature of a pizza. I have not ventured out to try other items on their menu, so you are on your own if you veer away from the pizza pies. My favorite selection is the Brooklyn Family, which features pepperoni, sausage, and basil on a healthy bed of cheese. "Healthy" in that context is a euphemism for "a lot". :)
Anyways, this location is usually without a wait and while the preparation of the pizza can take 25 minutes, having a garlic cheese knot order to wait is an excellent choice.
