Bottom line first: Don't waste your money. The World Aquarium is located within the City Museum in downtown St. Louis. Apparently, the City Museum is not a real museum but a place where about 1,000 kids are allowed to run free and scream and yell at the top of their lungs while their parents walk around bewildered. The so-called aquarium was a sad, dirty place with very little to see and nothing of value. It reminded me of some dude's basement where he "keeps his fish" but rarely ventures down the stairs to care for them. The City Museum cost $12 plus another $6 for the aquarium. This was the biggest waste of $36 Kathy and I have spent in a long time.
