Peachtree State GA2 was a restaurant, grass strip and a small museum. I think there's a flying club with a taildragger.
There are two places at PDK. Both good in my opinion. 57th Fighter Group is high end with a great Sunday brunch. The Downwind is more casual with a great view of the action.
LZU has The Flying Machine.
I've flown my wife to Jekyll Island for the day. Rent a red bug electric car and tour the island.
St. Simons Island is more developed and has a great amount of shopping, bars and restaurants.
Amelia Island is a nice stop. So is St. Augustine.
You can fly into FFC and get a ride to Aircraft Spruce. Not the biggest showroom, but they have most anything you want in the warehouse.
