What facilities in Atlanta have decent and affordable ballroom and event space.?

I'm not sure but sometimes they have ads in the paper. Also try asking a wedding/party planner.

Try King Plow. Do a search for "King Plow Atlanta."

Try http://www.lionscenter.net

Make sure you go see the facility and discuss the major and minor details to make sure they can honor your requests completely. You may be looking for something more fancy or maybe not. Just make sure you visit before you get too far into the details with them. The pictures on the site was probably done when the facility was first updated.

If you have a small party, you may try Deborah's Place 4600 Rockbridge Rd. in Pine Lake (Stone Mountain) (404)578-6882

Hope this helps
