This show is stellar in the evening! The show is every 15 minutes and is the length of one song. If you are viewing the show and can’t find a good viewing spot- just wait until the current show is over and the people there will leave. Then find your spot and wait a few minutes for the next show to start.
Each show is different. If you have time to view several shows it’s worth it.
Also a great spot for background shots of Paris.
