The smaller ones are my favorites, even though I've seen groups at Texas Motor Speedway, American Airlines Center, etc. Big names often require big places to hold all their fans.
Chung, please forgive me, I know we're commenting on local venues but I want to give a shout out to those who travel around a bit and make a highly respectful recommendation for the Fox Theater in midtown Atlanta. If you go there once, you'll always be drawn to trying to get back.
The place was built in the 20's and it has this Egyptian interior decor. The acoustics are second to none in the country and it's received several rewards for it's value as a superior venue.
Many many years ago you could go to Tarzan movies there and the Tarzan actors would show during intermission plus other stars from other movies. Sometimes there would be Duncan Yo Yo contest for kids during half times of double features. Elvis and The Stones played there on occasion as well as many other popular groups.
It has a rich history:

Today, you can watch AXS TV and see groups like the Allman Bros., Lynard Skynard and other well known groups playing there.
And the place only holds a tad over 5,000 butts !
