Go see Absente in the tent in front of Caesar's. Probably the most I have ever laughed at a show.
Go see any of the Cirque de Soliel that you can get tickets for starting with O. Don't waste your time on the sex one, cheaper just to go to a strip bar and the magic one ... Chris Angel? - is lame as fuck. Any off Broadway shows there will be quality. I saw Jersey Boys there.
I hear Celine Dion is good for low estrogen levels. I have not been.
