We visited two years ago.  Lots of history of the game with well done displays.  Be prepared to read, because each area has a ton of information printed on large posters.  In the basement there are probably hundreds of bowling balls from all eras.  We had fun looking at those and imagining how they fit the hand.  There are  old lanes that you can walk behind and see where the pin chasers worked.  Then there are two sets of lanes, one Brunswick and one AMF, that you can bowl on.  They're supposed to be latest scoring and surface technology, but when we were there the Brunswick stuff was at least one generation behind what we had in our new center.  Don't bother taking in a ton of your own equipment.  When we bowled, the lanes were drier than dry, to the point where I, a fluffer with no hand (at that time), was hooking plastic most of the lane.

Have fun!
