Quick NOLA restaurant question....

Cajun comes from South Central to South West La. the cooking here was influenced more by Creole which was a mix of African and French cooking.
But New Orleans has been heavily influenced with Cajun since Prudhomme first came into town. Mostly influenced with spices. But Cajun is more country home cooking.

If you are looking for classic and haven’t been to Antoines check and see what there lunch specials are. They might be doing their 20 dollar three coarse meals. It’s fancy as in classic old school but since Katrina there really aren’t too many places that require tie and jacket but ask at any rate with any place you call.
Commanders has done those specials at times also and that one should be on everyone’s bucket list. Pretty sure it is still coat and tie though.

both of those places do the specials in the summer and may be extending them now IIRC
