We visited the arch in St Louis but we did not go into the visitor's center. The river next to the arch is still very flooded. There are places roped off where you can not go at this time due to flooding. The arch itself is a must see if you are in or around St Louis. I'm sure the visitor's center is nice as well, we just didn't have enough time to go in to it.
