I'm giving this place five out of five because it's got the kind of atmosphere that I love: it's dark, out of the way, and whoever runs the place doesn't talk to customers or bother you about anything you're doing. Of course, I haen't the slightest idea who was in charge anyway, since no one was talking to anyone else :)
The only drawback to the darkness is that I felt like I was going to have my purse lifted. While playing pinball, I sqaushed it squarely between my feet where no perps could get near it without me knowing.
The giant warehouse of fun is packed wall-to-wall with older pinball machines, video games (the original Mario Bros!), and other neat stuff from an era that I am too young to have experienced. In fact, even my 40 year old man was too young.
This place is definately worth checking out. If you're a stuck up person who visits Vegas only to hang out on the strip and aren't interested in culture of any kind, you'll hate it here. Which is fine because you aren't wanted anyway. But if you're smart enough to appreciate relics from a time when video games required a little more effort (like standing) and more skill (like button pushing) and you love dark creepy places where no one bothers you, you'll love it here--just like me.
