Fave things to do in New Orleans. Have been but was always consumed w sports. Like jazz clubs people culture experiences food dance.
I lived there for years. Firstly, avoid Bourbon Street like the plague. The best stuff is where the locals go, not where the tourists go.If you want music, go to Preservation Hall, or http://goneworleans.about.com/od/nightlife/tp/JazzinNo.htmFor food, go to Nola, Emeril's, or http://www.frommers.com/destinations/neworleans/20_inddin.htmlor http://www.neworleansrestaurants.com/restaurants/Again, avoid any place that are tourist driven, they are still better than any other place in the country, but not to die for great like others.
Since you like Jazz, I would go to some jazz clubs and things like that. Also, you should enjoy the food that they offer down there. The culture their is amazing.
