On December 14, 2004, Prairie Meadows added casino game tables after receiving state approval to do so. As a result of the high demand for these tables, the Iowa Racing and Gaming Commission approved Prairie Meadows' plans to expand its facility on January 25, 2005. Construction on the $60 million expansion began in September 2005. An addition to the casino opened in August 2006, while two new restaurants and a 1,200-seat concert hall known as "The Meadows" opened in February 2007.
