I took my daughter here, since she's a fan of these kinds of shows, and I'll start by saying that the booking process is horrendous. It was difficult for me ( using the english web page) to even figure out HOW to book tickets, what 'additionals' went where, and for how much, etc etc.
In the end? I had to resort to 'show only' tickets - the resulting confirmation had the wrong number of people on it, AND the wrong time.
No worries - we went to a nearby cafe and had dinner, to return.
The show itself though, was fabulous. The acts were all very well done. The costumes were flamboyant, and the singing / lip-syncing were all spot on perfect.
For non-French speakers - many of the songs are in French. Some seem to be 'inside cultural caricatures' - but you cannot fault a French show, in France for doing French things!
My only issue was with the booking / administrative aspect, which could be improved with some web site work.
