I'm an SF hound and I'll be in Atlanta at the end of the month, staying at the Omni Hotel. Where should I eat great food for both dinner and lunch within walking/MARTA/short cab distance where I won't feel strange dinning alone? Like, places that serve at the bar? Any cuisine is fine, although local specialties would be the most fun. I'd like to spend under $40 including tip for dinner and under $15 for lunch.
