On a Street Corner in Paris

 As we get ready for our trip to Paris next week we are working out our schedule of not to miss places.  Of course we will drag ourselves out of bed early to hit this flea market, our favorite our first morning.  Other things on the list this year is a stop at BHV and their wonderful cabinet hardware for a job we're working on now.  We've secured our tickets to a concert in the breathtaking Sainte Chapelle Chapel.  Dinner is reserved in Eiffel 58 for a special evening.  We even asked the US Embassy if they had anything planned for the 4th of July but alas they diu not.
What is on your must see/do list for Paris?
