Pinballs!!!
This place rules! It's a dark but huge room full of nearly 100 pinball machines of all different types. If you enjoy pinball, you could seriously spend hours here just playing all different kinds of games. Because I sucked, I spent $5 in about an hour playing.
It was really cool seeing the early built pinball machines as well as modern machines. There's definitely a big difference between them too.
It's located in a strip mall a few miles from the strip but isn't too difficult to find. Highly recommended!!
