Part circus, part cabaret and altogether outrageous, Spiegelworld’s Absinthe isn’t so much a Vegas must-see as a must-do; the nearly 10-year-old show has become a rite of passage. Being insulted by the Gazillionaire, seduced by the Green Fairy and dazzled by Absinthe’s contortion and acrobatic acts are experiences every Vegas visitor should have. Caesars Palace, 702-534-3419.
