Rathbun's is always an excellent choice (not Kevin Rathbun Steak - haven't tried that yet).
Go off the beaten and try Noni's on Edgewood or Top Flr, corner of Ponce and Myrtle. You'll be pleasantly surprised by these neighborhood gems.
I very much liked 4th & Swift (except it could visually pass for Rathbuns - small complaint).
Floataway is an excellent choice as is Watershed, in Decatur. Wisteria is an overlooked treat.
Brick Store Pub for the best beer selection in the Southeast.
Highland Bakery or Sun In My Belly for brunch.
I do have a car, and don't mind traveling too far. I would say Buckhead is the furthest. I'd say price range is $150 for two people to eat and have a drink. My favorite types of food are steak and sushi, but i'm open to anything if it's good. Looking mostly for dinner reccomendations.
For Steakhouses, I would recommend Bones. There is an agrument over what is the best steakhouse in Atlanta and Bones is one of the names that consistently comes up. I prefer it infinitely more than Chops and consider McKendrick's a not so close second.
If you like Greek, Kyma is excellent for upscale greek. The mezze style dinner is very good as are the various fresh fish.
Home is another in the area, but Richard Blais is no longer in residence. The food is still very good. It is southern homestyle cooking with a Blais twist, so be prepared for some adventures.
I will think of more and add to this but this list should get you started.
My favorite spots:
Repast- in midtown sort of very close to your hotel
Baraonda- affordable Italian, great atmosphere, in midtown
Restaurant Eugene, been once and really enjoyed it, south side of Buckhead
Floataway Cafe, in Decatur/Highlands area
MF Sushi is good and not far from your hotel
Room at Twelve is very close to your hotel and serves steaks and sushi. You could knock it out in one shot. A picky friend of mine said he had one of the best steaks there.
Would like to try:
Cakes and Ale, in Decatur
4th and Swift, near Repast in the Old 4th Ward which is not too far from your hotel
