The series, executive-produced by Vince Vaughn, Peter Billingsley and showrunner Rob Long, takes place in a popular bar — Sullivan & Son — that serves as the unofficial "town hall" in a working-class Pittsburgh neighborhood.

Also featured are Lombardi's Dan Lauria as bar owner Jack Sullivan and Jodi Long, who was seen on Broadway in Flower Drum Song, as his wife, Ok Cha Sullivan.

The cast includes Steve Byrne as Steve Sullivan, Vivian Bang as Susan Sullivan, Valeria Aziynn as Melanie, Owen Benjamin as Owen and Brian Doyle-Murray as Hank.

As the series opens, according to TBS, "Steve Sullivan (Byrne) is a successful corporate attorney from New York who brings his girlfriend, Ashley (guest star Brooke Lyons) for a visit just as his Irish-American father, Jack Sullivan (Lauria), and Korean mother, Ok Cha (Long), are preparing to sell the bar and retire. Upon arrival, Steve reconnects with his best friend, Owen (Benjamin); gets accosted by his long-suffering, under-appreciated younger sister, Susan (Bang); endures offensive comments from gruff barfly Hank (Doyle-Murray); and gets hit on by tipsy cougar Carol (Ebersole). He even feels a rekindled romantic spark with his former sweetheart, Melanie (Azlynn). It doesn't take Steve long to realize that what he really wants out of life is to return to the old neighborhood and take over Sullivan & Son, even if it means giving up a lavish Manhattan lifestyle with the gorgeous Ashley. And so begins Steve's quest for a more meaningful and rewarding life behind the bar."
