Opened is 1986 as the Bluffs Run Greyhound Park, the Horseshoe Casino is now a Harrah's property near the Missouri River in the Omaha suburb of Council Bluffs, Iowa. Boasting over 88,000 square feet of gaming space, including table games, slots, and the dog racing for which it got its start, the Horseshoe is one of a handful of casinos in the area which have grown to thrive in the wake of recent liberalization of Iowa gaming laws.
