For Catfish in New Orleans I highly reccomend two places and one is classic Roadfood. Middendorfs in Manchac, LA (I55 between Hammond and LaPlace, only exit) has been serving catfish since the thirties. They have two styles of fillets and whole. I prefer the thin fry with a side of stuffed crabs. Mike Andersons in Baton Rouge and New Orleans also does a fine job with the grease and the corn meal.
