Vince Vaughn and Peter Billingsley are the executive producers of the pilot, which was written by Byrne and executive producer Rob Long.
"Set to begin shooting later this year, 'Sullivan and Son' takes place in a popular and legendary neighborhood bar in a working-class neighborhood in Pittsburgh, Pa.," TBS said in a synopsis. "Filled with locals and regulars, Sullivan and Son is the unofficial town hall to the neighborhood. Steve Sullivan is the son of the current owner of the bar and the grandson of its founder. His Irish-American father and his Korean-American mother never expected their son to leave his job as a successful corporate attorney in New York and return to the old neighborhood to take over Sullivan and Son. But that's just what he's done. And so begins Steve's quest for a more meaningful and rewarding life behind the bar."
