re: Acadiana Cajun restaurant recs

Plate lunches are your best bet for authentic cajun cooking, Saturday makes it tricky because most are closed or don't have Sat. lunch specials

Noah's Saturday options:
Smothered oxtails - grilled pork steak - fried pork chop - red beans/sausage - baked chicken

Poche's Saturday options: (haven't been since pandemic so not positive if still the same):
Pork Backbone Stew - BBQ Ribs - BBQ Chicken - Stuffed Pork Chops - BBQ Ribeyes

Suire's Grocery: changes but they've been doing spaghetti on Saturdays, they have good cajun foods on their full menu, mmmmm and some homemade tarts.

Johnsons Boucaniere: you mentioned boudin, you won't be disappointed here. Think they bbq on Saturdays or just stop in and get a few links.

Laura's 2 - Bourdain went to Suire's, he went here too. Haven't been on a Sat but I think you could go get a stuffed turkey wing.

The French Press: brunch spot downtown. The favorite, the cajun benedict (eggs benedict with boudin topped with two poached eggs and chicken and sausage gumbo) or the grits and grillades will give you what you're looking for.
