One side note - I have talked to several people who have been to Paris, but did not take the elevator up to check out the view from the tower. That was because they were visiting someone, and apparently Parisians consider the trip up too touristy. The view of Paris spread out for miles was reward enough, but adding the little S&P shaker to my collection was a definite bonus!
