Check groupon.com for at least a 50% coupon to get you started. I grabbed $10 in tokens for $5. That will get me warmed up. There are other deals for tokens upon arrival. Read the signs or ask the employee.
I was there to play the pinball machines. Most machines were "LE"s (limited addition) models and in pristine condition. Some had tasteful modifications that added to the games play or aesthetics.
I also liked how you're allowed to bring in drinks from the outside. Water, soda and of course beer and other alcohol. Not sure about food?
Also a big plus was the location, it's back in a nook. Off the main path of Freemont street where it can get a little weird and sometimes "unsafe". The staff was nice and helpful.
Enjoy ! I will be back, and back.... and back. This is a great alternative to the Pinball Hall of Fame.
