Will be in the area for business Monday night. Any outstanding restaurants near by?
Suggest you search this board and elsewhere for Decatur, which is reasonably close to Stone Mountain. Downtown Decatur is quite the dining scene with several good choices and a wonderful atmosphere.
If you are into ethnic hole-in-the-wall type food, you can take Memorial Drive towards Clarkston, there will be a few interesting spots on either side of the road. Primarily African (Somalian, Ethiopian, Eritrean, Nigerian, Liberian), but also Haitian and other Caribbean.
