We did a cooking class at
New Orleans School of Cooking a few years ago. It was fantastic. We'd walked under the sign a thousand times over the years but it just looked like a storefront selling sauces/spices/aprons/etc. We ended up cooking our best meal of that particular trip.
Manolito is awesome cuban drinks and cuban sandwich. A lot of tropical and tiki standards were born from the cuban hotel/vacation/party scene pre-Castro. I recommend being at the door when it opens at 4pm as it is very small and fills up fast. Don't sleep on the Cuban sandwich - it is one of the best I've tried. It is perfectly sized for 2 people to share as a mid-afternoon snack without killing your appetite for dinner. Their food menu can be found on Yelp but I've never found it on their website.
Keeping with the tropical/tiki theme (always an undercurrent in Nola fruity drinks) -
Latitude 29 is great. Reservations recommended here as well. Depending on when you want to visit there may not be availability. It doesn't open until 4pm. The ownder is 'famous' in the tiki world as he spent years digging up old tiki recipes from the original inventors and writing multiple books on those recipes. Tiki drinks have been *******ized over the years into complete crap drinks that bear no resemblance to the original. Best example is the classic Mai Tai. On 99.9% of menus that means "heres a few fruit juices and a couple of rums, the last being a dark rum float" which is BS. Not at this joint.
For music I would seek out
Charlie Halloran. He's a regular at the Spotted Cat on Frenchmen. World renown trumbone player. He and his band The Tropicales are absolutely fantastic live.
Staff - take out the trash.
