Easily the most unique show in Las Vegas. If cursing, racial stereotypes, or vulgar descriptions of sexual situations makes you queazy, then I would stay clear of this show. However, if that type of comedy and entertainment if right up your alley, you won't find a better show. When I sat back and thought about it, there probably isn't another show in town that can compare. My group and I all LOVED it and laughed throughout. It is almost unnecessarily vulgar and gratuitous at times but that was part of what made it so funny. You almost can't believe what they are saying/doing and can see other people looking visibly uncomfortable.
Absinthe is located in a tent in front of Caesar's Palace. It is not a huge venue so I don't think there is a bad seat in the house. Everyone is right on top of the action which adds to the excitement. Being a few feet away from a man spinning around on roller skates holding a woman from his neck is exhilarating and scary at the same time. Absinthe is also unique because of the crowd interaction. The host or "Gazzilionaire" as I think he was called plays a lot off of the crowd...so depending on who is in attendance, the show could very from performance to performance.
One tip...if you aren't someone who has poor vision or absolutely HAS to sit up front, I wouldn't worry about going for a cheaper ticket option and sitting further away. We had the most expensive ticket which included a (very small) bottle of champagne and ended up in about the 3rd row I think.
