Which theater is consistently rated for comedic productions?

Whole World Theatre on Spring Street in Midtown is a comedy improve theatre that keeps em laughing.

Whole World Theatre is very funny.  You should also try Dad's Garage Theatre off Elizabeth Street in the Inman Park neighborhood.  They have improv every Saturday night at 10:00 pm, and some rather funny productions on other evenings.  Their website is: http://www.dadsgarage.com/.  

I have yet to go, but I also hear Sketchworks is funny too: http://www.sketchworkscomedy.com/. 

Keep on laughin'!
 

For some good old fashioned stand up comedy, I love to go to The Punchline off of Hilderbrand drive in Sandy Springs. They book some of the top comedians out there.  Each time I've been, I've laughed until I cried!

Their website is www.punchline.com. You can check their schedule, purchase tickets and even pick your exact table, all online!
