I lived in NYC for four years and love the New York Style pizza, with huge floppy pieces. Zio's is the closest I've found in the area to that style of pizza. And they're open until 4am. So it's great late-night, bars-are-now-closed food. You can get delivery, but it takes an hour (even though I live 0.1 miles from their store). I would recommend pick up. The garlic knots are worth getting as well, they are greasy and doughy and delicious. You can dine in, but the pizza ovens make it a little warmer than I like and there are only hard seats so it's not super comfortable.
Zio's is a great place to get pizzas for parties or late night drunk food. Do it.
