Let's see if I remember what I did down there.
There's a BBQ place called the Joint that's not too bad. Ate there when I moved my brother and sister in law down there.
I'm not a seafood person so I can't really recommend too many places but the places of names I remember that I enjoyed ,Acme Oyster, everyone I was with seemed to like the oysters, I had a roast beef sandwich that was great. Johnny's Po Boys, was really close to our hotel, good little place. Crescent City Brewhouse, not a bad little brewpub. Rehersal dinner was there so I can't comment on the food normally, but I enjoyed the beer.
I drank a lot that week though. So I can't tell you the places I went at night, but I drank a lot of rum drinks. Figured when in Rome.
