lsxtreme,
from kennesaw, here's the simple directions. south on 41, left at the big chicken, it will then be about 1/2 - 3/4 mile down on the right.

Alternate directions... 75 south to 120 loop, left off ramp, exit 120 down onto roswell road, make a right off the ramp, then it's about a mile and a half down on the left.

It's across from Williamson's Bar B Que.. I'm sure you'll find it.
