"Rolled" in powdered sugar? They're buried in powdered sugar. You can't inhale as you eat them. Oh, yeah. Laissez les bon temps rouler!!
Some other thoughts I've had since I posted:
I've always stayed away from the old, famous restaurants (Antoine's and Gallitoire's -- excuse any spelling). My tastes are very much Cajun and some Creole, not French.
Emeril's places get lots of attention: Emeril's, NOLA, maybe others.
For a real local's place, go to "Mothers". You want a "Debris biscuit". The people I ran into down there say "DAY-bree" Not "dah-BREE". No idea. https://www.mothersrestaurant.net/
One of the most famous places is Willie May's Scotch House for fried chicken. Is on many lists as one of the best places for fried chicken in the world/solar system/universe. It's on my to do someday list. I think the original was wiped out by Katrina, but the community rebuilt a new spot quickly (or something like that).
My sister (who spends time every year in New Orleans, her daughter lives there) likes John Besh's places. Besh was under the radar for many until he became a Iron Chef. I don't know which of his restaurants she goes to, but I would guess Borgne
I haven't done many of the city activities. When I've been in New Orleans, we usually spend time eating and drinking. With three friends, we spent an entire day eating raw oysters, drinking beer, and watching the college basketball games on the TV. There's an aquarium. There's a zoo. There's a WWII museum (founded by Stephen Ambrose, I wouldn't miss it on my next trip).
For Sunday brunch, Brennan's is the most famous. They serve more eggs than any other restaurant in the country (probably most in the form of benedict). It includes jazz.
