My catfish suggestion is Catfish Jim’s on Cobb Parkway (US 41) in Kennesaw.  The best Cajun is at Gumbeaux’s in downtown Douglasville.  A close second is Henry’s Louisiana Grill, 4849 N Main, Acworth.  For bbq, I would suggest Fox Brothers on Dekalb Avenue in Atlanta.  Also well worth considering are Dave Poe’s BBQ on Whitlock Avenue in Marietta, Sam’s BBQ 1 on Lower Roswell Road, Marietta.
 
Now, you will hear from those who disagree with me.  They will provide their suggestions and Roadfood will be what it is – a group of people sharing their thoughts about food. 
 
After your trip, please let us know where you ate and what you thought of each place.
