Outside an unassuming white tent in Caesars Palace’s open air Roman Plaza, a line of people snakes around an empty, enclosed courtyard. It’s a Tuesday and beyond the line and the tent, the performers of Absinthe ready for their first two-show night of the week. But instead of joining the patient, hushed queue waiting to enter the theater, I’m being led past the line, into the tent’s small lobby, through the moodily lit theater and back out into the hidden, outdoor backstage area of Absinthe.
