I've seen this show twice, which is two more times than I've seen most shows in Vegas. I come to town to be a degenerate gambler and I don't usually take breaks. However, I really enjoyed all aspects of the performance.
Absinthe has a great combination of acrobatics, stand-up comedy, showgirls, and very very off-color humor. Some of the acts changed between viewings, so it remained entertaining.
I enjoyed the intentionally offensive humor, but your grandmother might not. So, bring folks you can look in the eye after your run-of-the-mill sex joke.
