My wife and I stopped into this very unique place when we had a little extra time on our hands in Amsterdam. I learned a few new things I didn't know about the human body, plus was motivated to live a healthier life style after seeing the appearance of organs from people who smoked, drank, etc. It's currently rated the #30th thing to do in Amsterdam, which I think sounds about right. It's worth of a visit, if you have time, but not a "Top Ten" experience in this amazing city.
