We went here recently, the last time it actually rained in Arizona. We arrived right when they opened, so it was not crowded at all for the first few hours. The bowling area is very clean and has a good atmosphere. After we finished bowling we went to the arcade section where they have a pretty cool laser "mission impossible" type game room where you are timed and have to avoid lasers in the dark.
It was a fun place to go. Even better if you are able to find a coupon or groupon. But I would definitely recommend arriving right at opening time in order to have a better experience.
