Hummm - Bones is not casual but it's in Buckhead and a really great steakhouse. I love Buckhead Diner but it's been years since I've dined there. Try to be a little more specific - what are you looking for? There are tons of taco places there now.
I just want a good meal at a decent price. Don't want to spend a lot. This is just a stop on our way to North Carolina. How about a good burger? Or good salads? Or some good fish? But I do not want a high end meal since I can get that anytime. Thanks!
If you want something different try Fado's in Buckhead it's an Irish Pub and the food is really good. Or Italian you can try Maggiano's I love their food, there are so many places in Buckhead that are good it's hard to pick out one or the other.
