Cilantros is another good one, my wife and I hit the Woodstock location attached to the shell at 92 and Main Street. Hole in the wall but fantastic Food.Man! Since op talked about " home cooking"(country kitchen), this is the place that popped into my mind.
Dougs is fantastic. Its hard to find chicken livers anywhere, and Im pretty stuck on that when I go there.
Also in the kennesaw area is Colombian Bites right behind kennesaw barber and the old library. ****ing delicious. Also cilantros is damn good too and ita somewhat a hole the wall.
