I'm going to be in Atlanta for the next few days. Any must-try food there? I'll be in the downtown area and won't have time to go much outside of that.
Depends on how much time you have any what level of food you want to try. Decatur has some good places. I will list a few things off the top of my head although it's been a couple of years since I was living in Atlanta.
Steakhouse | Decatur, GA - Parker's on Ponce - Good for a decent steak nothing to fancy.
Brick Store Pub - Has a pork belly sandwich that is fucking awesome. Plus a retardly large beer selection.
The Iberian Pig - Is also good tapas type restaurant
Rathbun's Restaurant's Official Site - This place is well known and it really fucking good but costly. Still the steak here is some of the best I have had.
MENU – CANOE ATLANTA - Is good if you want something different "Rabbit, Duck, Venison" last time I was here they had stingray.
Bone Garden Cantina - If you like as close to authentic Mexican food as you can get outside of Mexico. Then I can't recommend this place enough was always one of my favorites.
There are a couple of these stores called "Atlanta's Best Wings"
Atlanta’s Best Wings - Decatur, GA
Atlanta’s Best Wings - Tucker, GA
They are run down looking niggity nog type places that almost look shady as shit, but goddamn they have some of the best mother fucking wings you will find. Top notch
For fast food you can try Varsity since that is also an Atlanta thing it's a burger and hotdog joint but really isn't anything special. Then again McCheese is known for stuffing vile shit down his gullet so maybe it's perfect.
That is about all I can come up with off the top of my head. If I can think of something else maybe I'll add to this but go to BoneGarden 100% and snag a big box of fucking wings at ATLbestwings.
