Piadina is one of our favorite places to visit whenever we're in New York City. There are a few things to remember: They are only open for dinner. They only take cash (and there's an ATM on site). They only take reservations if your party is six or more. Other than that, this place is amazing. The staff is wonderful, friendly, welcoming. The ambience is cozy and authentic. And the food is beyond beyond. We have never ordered anything there that wasn't delicious. One of our favorite things to order is the polenta appetizer (smothered in melted gorgonzola). Go there once and you'll become a regular.
