Raise a glass! Atlanta-based TBS has renewed ensemble comedy “Sullivan & Son” for a second season.

The sitcom, set in a bar, concludes its first season’s ten episodes next week and has averaged a solid 2.5 million viewers a week since its debut in July.

The pickup is modest: 10 more episodes for 2013.

“Sullivan & Son has gotten off to a strong start, quickly building its own fan base,” said Michael Wright, president, head of programming for TBS, TNT and Turner Classic Movies (TCM), in a press release. “We look forward to seeing the show continue to grow in 2013.”

In the show, Steve Byrne plays an attorney who his career in New York City to run his parent’s Irish bar in Pittsburgh, where a cast of wacky characters reside. Byrne, a veteran stand-up comic, last month visited Atlanta for a show at the Punchline.

TBS over the years has struggled to develop original programming that sticks. While “Sullivan & Son” is not necessarily a “game changer” for the network, it did well enough to merit more episodes. The network also renewed another ensemble comedy “Men at Work” earlier this year for a sophomore season.

Right now, the network is riding high thanks primarily to repeats of ‘The Big Bang Theory,” which is boosting ratings for “Conan.”
