$30 per person does NOT make a party!

I'm currently dealing with a boss who thinks we can swing a nice holiday dinner party at a restaurant in Atlanta for $30 per person.  You can barely get an entree and a drink for that, and that's not even considering room rental fee for 35 people, open bar, appetizers, desserts, service charges, etc. 

So I think we've changed the plan and are going for a cocktail party with heavy hors d'oeuvres feel, hopefully in a restaurant that feels festive and party-ish.

Anyone have tips for very good party vibe restaurants in Atlanta?  Help!
