Anthony,
For seafood, go to Atlanta Fish Market (owned by same group that owns Chops:
http://www.buckheadrestaurants.com/home2.html) Fogo de Chao is a great experience and the food is very good (in fact we have plans for later in the month) but do make reservations ahead of time especially if this is on the weekend...For Italian we love Dominicks (if Bobby is there tell him that you were referred by Chuck & Ronnie) but that is in Norcross about 30 minutes (not in rush hour) north of the airport but the food is great !! If you want wonderful sushi and great live fish, go to Asahi...it is also further north but well worth the drive and easy to get to as it is on 85North at Jimmy Carter Boulevard (if you go tell Sato that Chuck & Ronnie recommended it and he will take care of you)...
Here are a couple of reviews:
