Awesome doesn't cut it. This place offers the most fun you can have in Vegas for the least amount of money -- we spent $10, were there for 2 hours and could have stayed all afternoon for not much more of an investment.
We had no idea what to expect -- a room with really old or broken pinball machines behind ropes? A bunch of plaques with high scores on them? An exhibit on how the machines work? A gift shoppe? Nope. None of that.
When we walked through the very unassuming door we were greeted by familiar dinging noises and basically an old-school arcade -- really just a warehouse filled with pinball machines and some great old video games...and you can play ALL of them! A bunch of machines were just 25 cents per play (3-5 balls) and I didn't see any that were over $1.00.
There were only about ten people there when we went (mid-day on a Wednesday) and we will go back to this place every time we're in Vegas. SO worth the little trip off the strip!!
