Suggestions for best places to eat....

I will be visiting your fair city next week, and I am a bit of a foodie! I will be using yelp and urbanspoon of course, but any suggestions for must eat places?
for some good Southern cooking, try Greenwoods, in Roswell. But bring your appetite, they will bring you lots of food!
I actually like Greenwoods, too. Not sure, though, if it will meet your definition of must-eat as a self described foodie. I tend to like more casual, low-key places, and Greenwoods fits that description.

What kind of food, price point, part of town are looking for?
