I've lived in the neighborhood for going on 15 years, and this unassuming neighborhood pizzaria has been my fave the entire time. I agree with the other comments already posted, but let's cut to the chase: these folks make an outstanding Neopolitan style pie. Possibly the best crust of its type I've ever tasted--just the right balance of crispness and chewyness. The toppings are fresh and high quality. When you get tired of trendy, expensive thin-crust joints like John's, Pizza Park is the perfect alternative. And be sure to try the garlic knots!
Pros: Great Neapolitan pie, quick service, open late
Cons: generic atmosphere, sometimes crowded, Upper East Side, yuk!
