The Mirage Hotel & Casino has a volcano out front that erupts nightly on the Las Vegas strip.  Moreover, the Mirage also features white tigers that were featured in the old Seigfried & Roy show.  I never saw their show, but I have seen Cirque Du Soleil "O" at the Bellagio, Cirque Du Soleil "Mystere" at the TI, Cirque Du Soleil "Ka" at the MGM Grand,  Melinda, First Lady of Magic at the Lady Luck, King Arthur's Tournament at Excalibur, Dirk Arthur Magic at Silverton, American Superstars at the Stratosphere, & Bite at the Stratosphere.
