Investigators found that "line cooks did prep work off-the-clock before the start of their shifts, resulting in unpaid overtime work," the Labor Department said in a statement. "Servers and bartenders also worked — off-the-clock and without pay — to prepare food, the restaurant, and their individual work stations, resulting in minimum wage and overtime violations. The Division also found the restaurant failed to maintain accurate records of work hours for bartenders, servers, and line cooks."
