1. Modern Pinball in New York City is awesome. Get the Groupon and I think it's just $15 for 3 hours of unlimited free play.
2. SS Billiards in Minneapolis just because it's a great old-school spot.
3. Blainebrook Bowl just outside Minneapolis has a ton of pins.
4. And a certain private home arcade, a long drive out of downtown Minneapolis, would make your jaw drop. But you need to know the secret knock to get in.
