Hey Steve, when ya going?
My Navy son and D-I-L lived in Plaquemines Parish SE of NOLA for a few years while stationed there. Right across the road from the Mississippi River. No specifics on where to get what, but it all is truly an eating experience over there.
We used to hop on his dirt bikes and ride the hinter lands. Way cool, just not as cool as their present location up the PCH from Malibu.
Enjoy the adventure.
