DO NOT GO HERE! The ambiance appears great from the outside and I was charmed into going. The food was mediocre at best (how can a restaurant in New Orleans mess up crab cakes?) and the service was awful. When I asked around after our experience I heard many negative things about Cannons. The restaurant was pretty empty and yet our waitress was busy chumming around with her friends. She didn't bring water, she didn't empty our ashtray, she didn't ask if we wanted refills of our drinks, and she made us box up our own leftovers. She was nowhere to be found. There are plenty of good restaurants in New Orleans and this is not one of them.
Pros: ambiance, wine quality
Cons: service, food
