We spent 6 days in NOLA recently. These were the very best dishes we had. We obviously focused our choices on seafood.
Note that because we had two large dogs with us at all times (they stayed in the truck while we ate), we really couldn't dine in the FQ or CBD since it would have been impossible to park nearby. Thus our range of restaurant choice didn't include any in those areas.
Crawfish Tasso Cheesecake -- Dick and Jenny's
Charbroiled Oysters -- Drago's (Metairie)
Shrimp and Tasso Henican -- Commander's Palace
Butternut Shrimp Bisque -- Brigsten's
Praline Bacon -- Elizabeth's
Apple Pie -- Steak Knife
Thin Sliced Catfish -- Middendorf's
Shrimp and Fried Green Tomato Po' Boy -- Mahony's
Greatest disappointments were Mosca's (overpriced and past its prime) and Cassamento's (not overpriced but past its prime, but still does a decent oyster stew). We also tried the local Vietnamese scene including Hoa Hong 9 and Dong Phuong, both well worth a trip. And the beignets at Morning Call are as good as ever, much preferred to Cafe du Monde IMO.
