i am trying to plan a date in the french quarter that does not revolve around bourbon street. nor taking one of those horse carriages. is there something else fun to do besides drink?

When I was a graduate student in New Orleans some of my favorite French Quarter activities were to start with a lunch at Napoleon House. http://www.napoleonhouse.com/

Then move onto the Louisiana State Museum.
It is a wonderful museum with a delightful Mardi Gras exhibit featuring some historic gowns and "royalty" items.

Next up I would head over to the Museum of the American Cocktail. It is quick and fun.

I would then slow down and window shop (remember I was in grad school so I was not in the market to buy) the delightful shops of Royale. It has wonderful antique stores and art galleries for several blocks.

For a tourist with a much more generous budget than a student would have, I would wrap up the evening at Brennan’s. Which is famed for its Banana’s Foster and is reputed to have been the favorite NOLA restaurant of legendary actress Vivienne Leigh.
