Oh I could go on and on. So much to see and do there. The restaurant suggestions so far are great. I recommend a b&b in the garden district along the trolley line for easy access uptown and to the French quarter.
Another restaurant I like is the gumbo shop on St. Peter's alley I think ne'er Jackson square.
Try neworleansonline.com. Great website with outlines for Nola ina day a weekend , for romantics etc. I also did a fabulous walking tour of Garden district , raconteurs.
