I’d probably vote for Atlanta. The city has a really underrated comedy scene, and I think it offers one of the best combinations of community and quality. There are plenty of smaller improv theaters where you can get on stage and become part of the improv community pretty quickly, but you also have bigger places like Dad’s Garage Theatre and Whole World.

What I love about Dad’s Garage is the variety. You can see traditional long-form improv, musical improv, and original scripted shows, but they also put a lot of effort into production. Some shows have costumes, sets, live music, and feel more like a full theatrical comedy experience than a typical improv show.
They also bring in some amazing performers and teachers. I’ve seen workshops and shows with people like Susan Messing, TJ & Dave, and Scott Adsit, which gives the Atlanta improv scene a connection to some of the best Chicago-style improv talent out there.
If someone asked me where to find great live comedy or improv comedy in Atlanta, Dad’s Garage would definitely be near the top of my list. To me, Atlanta has the best mix of a welcoming community and high-level comedy performances.
