If you've never been to Atlanta, you should also stop by Atlantic Station during your visit! Although they don't seem to have a Sephora or MAC there, there's tons more to do there-- shopping, eating, and sight-seeing. Lenox Square Mall, however, does have a MAC and Sephora and is relatively close to Atlantic Station as well. Lenox is a great mall -- there's tons of name brand stores and lots of places to eat as well. The only problem you'd probably face is transportation and that's if you don't have a car. Oh, and also, Discover Mills is pretty far from downtown Atlanta. It's actually about a 30-40 min. drive away. Mall of GA is up north and is about 10-15 min. drive away from Discover Mills. Mall of GA isn't bad either. It's fairly new [built a few years ago] and also has tons of stores. But however, I just checked their website and I don't see a Sephora or MAC listed. Boo! Anyway, hope you have tons of fun! Now that I think about it, I really miss being home down south....
edit: I also forgot to add that Perimeter Mall also has MAC and Sephora. I'm almost sure [not positive] that it's close to Lenox Square Mall. Anyway, another mall you could try if you're in the vicinity.
