You can see Illuminations from Bistro de Paris (the restaurant upstairs in France). You would need to have a table by the window and there aren't many of those. It's also probably not the best view. DH and I had dinner there a few years ago and were lucky enough to have a table near a window and we actually could watch Illuminations and we could hear the music even though it was muffled because we were indoors. It was very romantic and we enjoyed it very much. However, I would say that if you really want to enjoy Illuminations, this is not the place to be. It's only nice watching it from there if you have seen it before and been able to fully enjoy it with a good view.
