The Atlanta Botanical Garden is nice (be sure to check out the mini rainforest in the Fuqua Conservatory) and if you’re with kids, the Children’s Garden is cute. Fat Matt’s Rib Shack is still an awesome place to visit and eat. Decatur is a great place to walk around, and there are many good restaurants a block or two away from the square downtown.
