The vortex has 2 locations, one on Peachtree and the other in Little Five Points (about 5 minutes from the Carter Center). It is 18 and up because they allow smoking, but it is some of the best inexpensive food in atlanta.
I so wanted to go there, was with a bunch of friends and we were walking around Little Five Points but nobody else wanted to stop in. err. Oh, well there is always next time.
They have some bizaare burger combinations, but they are oh so good!
