I have never been there but I sometimes use the cams to watch people at Bourbon St. and St. Peter. You can see and hear people there from two levels and they also have a cam inside a close by Kareoke bar. Grab a beer and just watch people in this last one. Hear the songs and have fun.
Yes, people. Cams like in the series "Person Of Interest" are here. News and weather people use them all the time.
I suppose it depends on what you consider "fun."
I don't drink, do drugs (except cannabis oil, taken to treat cancer) or do casual sex but I wouldn't mind listening to a live jazz band.
