Where is the Bar Food in Atlanta
Bar food to me: basic salads, burgers, chicken sandwiches, fried items (cheese sticks, chicken fingers, wings)that were previously frozen, bag-o-chips on the side.
The Earl or The Flatiron in East Atlanta
Brickstore in Decatur (pub food)
Righteous Room near the Highlands
Decatur is the only location accessible by Marta rail. East Atlanta & the Highlands would be a short cab ride.
Oh, and I also agree about the Treehouse in Buckhead. Excellent bar food and if the weather is nice, cozy patio. Could take Marta to Lindbergh station then really short cab ride to the restaurant.
All of these are also very "neighborhoody", local hangouts. If that makes a difference.
If you're thinking of it more in terms of pub grub as opposed to something fancy, there's a good list of place for burgers, fries, and the like. The Righteous Room, The Earl, The Flatiron, The Brick Store, 6 Feet Under (seafood), El Myr (burritos/quesadillas), and The Local (Q) all jump to mind. Euclid Ave Yacht Club, too, maybe, but I don't ever seem to get there to have an opinion on the food.
For fancier, Halo used to have small plates and things like the now-well-past-the-bubble smore kit. Or Woodfire Grill, though our one Sun PM experience was embarassing (for them). Noticed that Paul's in Peachtree Hills, like Woodfire, has a Sun 1/2-price wine special also. And I noticed that b/c we had just eaten at The Treehouse, which is a step up from the places above (but not as fancy as Halo or Woodfire) in terms of food. Nice patio for our generally-early dinners w/ the Chowpup.
The Vortex, which has locations in Midtown and in Little Five Points, is a great bar/restaurant with really tasty burgers and fries.
If you're looking for something a little more upscale, try Krog Bar (Inman Park) which has tapas-style small plates that you can enjoy at the bar. And ever since I had my birthday dinner at Rathbun's (same owner as Krog Bar) I've been dying to go back late one night just for their incredible dessert tasting menu and a glass of sparkling wine or sherry.
