First of all An Evening at La Cage is a very entertaining way to spend a couple of hours in Vegas. The performers are energetic, they give a great effort, and look like they are having fun. Yes, it is all lip synched, if you don't like that, you won't like this show. Lip synching like anything else is a skill, and some of the performers are better at it than others. The only time it really bothered me was with one specific performer who was not so good at it, at became very obvious and embarassing.
The "host" of the show is impersonating Joan Rivers, but really, Joan Rivers can only wish she looked half as good as this one. She (he) was very funny, and told some dirty jokes to loosen up the crowd. He was live, not lip-synched and really was good working the crowd.
Now the negative...
We paid for "premium" seating which meant close to the stage, and when we picked up our tickets the man said the premium seats also meant we don't have to wait in line. Great, so we took our time getting to the theatre. When we get there, we find two lines, one for regular seats the other for premium seats. There are already 20 people in line for the premium seats. When we ask someone about this they reply "this is how we do it" and are quite rude about it. After about 30 minutes standing in line (listening to a lot of other people with the same complaint) they finally let us in. In the "VIP" section there are 20-30 seats along the aisles (the best seats in the house) that have "reserved" signs on them. I assume these are for the people who tip the staff and the time share sufferers. We overhear many people ask about those seats only to hear "they are reserved" Well, guess what? No one showed up to sit there , and they didn't let people move. So picture a very small theatre, and the best 20-30 seats in the house are empty. Way to go guys! Bet that made the performers feel great!
The show is very good, but they really need to move it to a better casino with a competent staff, not a dump like the Riviera.
