If you need to eat something in the Grand Central dining concourse and have enough time for a quick sit-down meal, Prova Pizzabar is worth knowing about. In addition to the to-go pizza counter, there’s a little table-service area off to the side where you can sit and eat a massive $14 square pie in peace. It’s not the best pizza you’ll ever eat, but it is the best pizza you’ll ever eat while sitting in a semi-private space in Grand Central. Also - expect a bar where people drift in every 10 minutes or so asking for triple whiskeys.
