The Casino Windsor in Ontario is the casino that has been given the best rating. It is just across the river from Detroit. Who would have guessed? Seriously, however, there are three casinos in downtown Detroit that are not located on Indian reservations. The MGM Grand Detroit Casino has been given really poor ratings. Patrons recommend Greektown Casino, however, that doesn’t fare any better. You may want to try Motor City Casino and Hotel because at least this one was given a better rating for its games.
