I second FunSpot, and would suggest it as an "instead of" to Chucky Cheese. They have an enormous arcade (lots of games from the 80's and 90's that you didn't know still existed), a pizza shop, great bowling where you can do bumpers for the kids but no bumpers for the adults, lots of opportunities for the kids to earn tickets that they can exchange for prizes that are much better than what Chucky Cheese has, mini-golf, etc. It's a great alternative to Chucky Cheese. Check on-line or at local convenience stores for coupons that will give you an extra 50 tokens for your $20 purchase (instead of 100 tokens you get 150, which makes it about 13 cents/game). Just don't go if you're there during Motorcycle Week (June 12-20).
Funspot...The Spot for Fun!
ETA: If you're going to buy more than one batch of tokens, bring multiple coupons -- you can use one with every $20 you spend.
