Happy Herb Pizza
The thing to do in Pnom Penh is to find happy pizza place (one is right across the street from Foreign Correspondents Club) and get your pizza extra happy. Finish up with some local beer for the night you will (not) remember!

History
It is amazing to hear about all hardships that hit Camere people not that long ago. You should visit landmine museum and find out about how entire families were wiped out from the face of Earth in brutal killings. Stories you will hear are going to be very difficult to digest, but knowing more about them will make you appreciate Camere people even more.
