We've been here a couple of times now and my son loves it. The rooms are pretty clean and the staff has always been polite. I find the kids here to be pretty well-behaved and the parents more involved in supervision than in other locations.
One exception would be the woman who put her 6 mo old itty-bitty baby girl on the floor to crawl, then glared at all the 5 and 6 yr olds running around (and doing their best not to step on her). I really don't think infants should be allowed on the floor of the playrooms.
We're looking forward to trying the Parent's Night Out event this Saturday!
