Bobby Van’s is one of the better airport restaurants in the Priority Pass program. While you’re supposed to have a same day boarding pass to enter, that still lets you eat there both on arrival in New York and on departure as well.
In my experience they don’t actually check boarding passes, just swipe your card. If I were an American Airlines crewmember based in New York I’d definitely get a credit card that offers unlimited Priority Pass visits (not from American Express, which doesn’t cover restaurant visits).
