Yes they do have a drive thru and you enter on the south side of the building which is directly behind the restaurant and the window is on the east side.

No they do not.

Check out thier facebook page the list it sometimes.

I don't own the place, and I very seldomly eat there. With that said, I don't know if they have boiled crawfish as of now. It is still very early for crawfish season. Your best option is to call the place to find out if they are now serving crawfish.
