BBQ:
Neely's Interstate
Corky's
Commissary (Germantown)
Chicken .. Not that crazy about Gus's and rest are mediocre
Catfish:
Wolf Creek Inn (Rossville...East of Collierville) is hard to beat for fresh catfish and cold beer...usually standing room only.
For home-style Southern food, including lots of vegetables try Dales in South Haven on State Line Road
