I love visiting New Orleans when I'm down that way to see family but it's definitely not a place I will ever willingly move to. That being said, if you do decide to go to Cafe DuMonde, just walk around the line and go in the side entrance to find a table. Seat yourself and wait to order. Cash only there, though. And mind the wind direction. Powdered sugar everywhere! Haven't been to the zoo or aquarium in decades but Audubon park is great! Went the WWII museum decades ago, too. Some of my grandfather's pictures from his scrap book during his time in the Pacific ended up as back drops for the exhibits at one point. I should go back and ask if they're still up. Some of the best eats around are definitely the tiny mom and pop places! Don't just limit yourself to the stuff in the French Quarter but do mind where you go. Also, a trolley ride is a cheap, fun way to see the city!
