White Plains

Papi' restaurant is right across the street from White Plains Train Station. If you park in the lot right when you come down the train station steps, Papi' validates. They have awesome, authentic italian. But it's setup so it's fast food style. But, delicious, healthy, and they cook right in the open. Anthony's Deli is another good one. Both are on Google Maps.

As of now it's running I know.
