Mr. Selfish and I had our best meal in Paris in the 17th Arrondissement at Le Relais de Venise. The line outside is always ridiculously long and they don’t take reservations, but it’s worth of the wait.
The 7th Arrondissement, of course, has the amazing Eiffel Tower. But there is other stuff to do in the 7th as well.
One of the most beautiful sites is Les Invalides. It contains museums and monuments relating to the military history of France and, most significantly, is the burial site of Napoleon Bonaparte. Across the way is the École Militaire, which is a military school at which Napoleon studied.
