I *love* Chuck E Cheese. My children *love* Chuck E Cheese.
The worst thing about CEC is their food. It leaves much to be desired, but the kids dont seem to mind it, and the salad bar is satisfactoy. The cost without a coupon is a bit much too (ok a lot too much)
The best thing about CEC is that they will not let your children leave the room without you, so the older ones can wander around while you stay with the littler ones.
And if you can find a coupon (often Buy $5 tokens get $5tokens), it is well worth it. It usually takes us about 2 hrs to run through the tokens.
I'd avoid it on a weekend day, but for an outing on a weekday early evening, it is a great place for the kids!
