Need Recs for Hammond/Northshore/Slidell area

Got a friend of mine that's gonna be traveling through the state on his way to Tuscaloosa, will be hitting the Baton Rouge area around lunch time but wants to avoid the Friday traffic around campus and would rather bypass that part of town.

Any recs for the eastern side of Baton Rouge, and/or Hammond/Northshore? Something hole in the wall-ish preferred.

I told his silly arse to either stop in Layette or ride through New Orleans for some R&O's or something along those lines, but no dice.
