merci NY times For years now the crowds which descend on Las Vegas have demanded something more than just a sleezy show to entertain them. As more and more families become attracted to the activities and spectacle that is Las Vegas, demands for more wholesome productions has risen. In response to this growing sentiment many Broadway shows have come to Sin City in recent years (ranging from "the Lion King" to "Mamma Mia!"). As Las Vegas flagship hotels make desperate pleas for increased tourism spending in order to weather this recession, the advent of Broadway caliber theatrical productions gracing the famous "strip" may not be far off at all. For instance, the reliable "Lion King" will be opening this month soon to be followed by Cirque de Soleil.
