A couple more things:

For a real taste treat, and one that you do not find much in the US (although it may be the next food fad), try macarons, which two light meringue-like cookies (made with ground almonds, so if you are allergic to nuts, pass on this) filled with various flavored fillings. These are not like the cocunut macaroons you may be used to seeing in the US - nothing like them at all, though many people confuse them and never try a macaron in Paris. Many bakeries and patisseries have them. I like Gerard Mulot and have had many others, too.

For a unique look behind the scenes at various artisans and shops, look at Meeting the French (www.meetingthefrench.com) and then look for "Meet the Parisians at Work". We did the tour of Gerard Mulot (on two different trips, it was so good). Met the macaron baker and the chocolatier, sampled their creations, and heard about how they trained and how they create their macarons and chocolates. Helps if you can speak some French but many tours are also in English, which could mean that the artisan speaks English or that the tour guide can translate for you to some extent.
