cool restaurants in ATLANTA georgia for my 21st birthday?

I turn 21 the first week of January, and plan on inviting 20 people max to come out to a restaurant friday night. I have a few guy and girl friends who are still 20 yrs old so I need a place where they can come too.
I don't like the whole club or dance scene...I just want a fun place where we can still be loud. thanks!

I took my fiancée to Violette last Valentine's. It's a great French restaurant.

sundial or 1848 house!

Try somewhere in Atlantic Station. They are friendly for people under, 21 and over 21. I suggest Strip. It is a really fun environment, good food, serves drinks and also, has a clubby atmosphere, BUT it is upstairs away from everyone else so if you have some friends that want to go dance they can just go upstairs. It is a very nice place and the decor is awesome too. If you don't like this then try one of the other resturants, Atlantic station is the best place I believe for your age group.
