Anyone been out to La Geode in Paris?

Anyone been out to La Geode? I'm travelling to Paris with my kids and it looks like something the whole family might enjoy. Directions say its only about 15 minutes from the train station. Trying to see if its worth the ride there.

Hi,

I went there with my school when i was a child and more recently with kids !

I really enjoyed it... I think that's a good idea. :)

There is a lot of things in the "Cite des sciences". Things very funny with water, electricity, .... I recommend !
