another good view is from the top of the Arc de Triomphe. I like it a lot, and it has a good thing : if you are elderly, have some problem walking (or you are sporting an ankle bandage as I was in September 2001) or have young children ... you can get the lift almost to the top of the Arc. It is on the opposite "leg" top to the one you would be normally climbing through. Just go near the person in charge and look at him/her with sadness in your eyes ... BTW, with children, only one of the parents can go up with them, the other one has to climb :)

La Samaritaine is a good place, but I think that now you must have something to eat or to drink at their cafeteria in order to be able to enjoy their views.

And the thing I like more about the view from the Galleries Lafayette is the fact that it is right behind the Opera Garnier, and you could feel that you could touch it ...
