4th & Swift - haven’t been, can’t comment.
Aria - One of my favorites. Chef-owner Gerry Klaskala does particularly wonderful things with soups, seafood, and anything slow-cooked. Extensive wine list, but I’m not familiar with the pricing because I almost always take my own. Good atmosphere for a business dinner - upscale but not stuffy.
Abattoir - Have been, enjoyed it, but it’s not a regular destination. Industrial-chic setting, meat-centric menu, haven’t paid much attention to the wine list.
Sotto Sotto - One of Atlanta’s top Italian tables, IMO, with a deep, almost-exclusively Italian list.
As much as I like Sotto Sotto, for Italian (in this case, Tuscan) I prefer Antica Posta - http://www.anticaposta.com/wine.html - which also has a deep Italian list (especially Tuscan wines) but with more non-Italian selections, a very interesting ‘Reserve By-the-Glass’ list, and reasonably-priced corkage ($10, versus $30 at Sotto Sotto). Good atmosphere for business.
Empire State South - Most convenient to Atlantic Station of those you list. Another personal favorite. More casual atmosphere and noisier than Aria or Antica Posta, if that makes a difference to you for a business dinner. IMHO, the most interesting wine list in town - not as extensive as others, but thoughtfully constructed, reasonably priced, and well-matched with the cuisine.
Local Three - I dine there more often than any of the others on your list. Very informal, high-energy (read ‘loud’), welcoming, and friendly, with simple, tasty, well-prepared food. Any deficiency in the wine list is more than compensated by the corkage policy: bring all you want, at no charge.
Serpa’s - haven’t been, can’t comment.
Others to consider:
Restaurant Eugene - Atlanta’s best restaurant? Probably. http://www.restauranteugene.com/
Bone’s - If a clubby steakhouse with an excellent (though pricey) wine list appeals, this is the one. http://www.bonesrestaurant.com/
