I'll give you some local favorites in Roswell
Oak Street Cafe
http://www.oakstcafe.com/ - they have a spectacular weekend brunch. My wife and I also go there about once a month for dinner. I didn't like the way they switched the dinner menu to mainly sandwiches but they've gone back to a traditional menu now.
Roswell Tap - this is my local watering hole and Steelers bar. They have really good food for the type of place that it is and their smoked wings are GREAT. Since ownership switched, the drink prices are getting too expensive though.
Roux - Gumbo is excellent and spicey. Never had a bad meal there.
Cue BBQ in Alpharetta - the guy (Paul Doster) that started Que was part owner and operating manager of Swallow at the Hollow. He and the (liberal cretan) owner of Greenwoods (Bill Greenwood) had a falling out so he started his own place. SATH has gone down hill ever since. Que is like the original SATH but with an expanded menu. Great bbq and ribs.
