ONE FLEW SOUTH
If you have to be in the Atlanta airport I recommend One Flew South to eat and have a few cocktails. I enjoyed both there.
My favorites there where: The Sazerac, a neat Rye Whiskey with Absent and bitters drink that originated in New Orleans in the 1800's.
The Tuna Sashimi and pork belly where excellent my friend.

Finished my first Half Ironman 70.3 in New Orleans and it wasn't too bad. It was easier than one day in the Airborne Infantry! Hardest part was not drinking and partying too much in NOLA before the race. That was really tough.
