What can we expect in the Moulin Rouge? And is it worth the cost???

If you have never been to it, I would go. I went there while on my honeymoon. Some people say it is touristy, but I enjoyed it more than the others shows in town. It is in a bad part of town, but the Moulin Rouge is old. It has been there a long time. Considering how expensive Paris is, in general, I didn't find it too expensive for what we paid. If you enjoy the Vegas-type shows, you will enjoy it.
