Can you watch Illuminations from inside Bistro de Paris? If so, how good is the view and can you only see things if you're at a table next to a window?
We've had a window table facing the lagoon twice and there's not much of a view. The windows are not very large and there are trees blocking 90% of it.
If you don't have one of those window tables (there are maybe 4), you will not get any view.
