Just to be clear, I'm not
suggesting D&B, just mentioning that there is one, in case he doesn't venture out anywhere else.

If you're looking for pinball, your best bet in the 'area' is Pinball Parlour. Lots of pins, even a Medieval Madness. It's basically a two story garage. Not much on ambiance, but he's got games. Again, maybe about 45 minutes from Phila? Here's his Game List, which can also lead to Directions, etc.

They aren't always all up and running. He's got everything set to free play and usually when that's the case, they don't fret about one machine having issues as you could just move to another. I believe it's a one man job and probably very difficult to upkeep all those machines.
