Paris by Mouth also has a list of best baguettes.
A few terms defined: MOF (Betsy's post) Meilleur Ouvrier de France, an honor given to a tiny, tiny number of the best bakers, pastry chefs, chefs, furniture makers,--ie crafts persons. Chefs and bakers have a blue, white, and red ribbon around the collar of their uniform.
Richard (chexbres) a brand of expresso coffee.
Artisan boulanger-- a baker who makes his/her own bread from scratch. Why do we need this designation? Because many, many bakeries sell factory bread they only finish baking--including some of the places mentioned in this thread, which goes to show the power of suggestion! Yes, even pastries that look so yummy and sophisticated, may come from a factory (explains why so many bakeries carry the same few pastries).
Look for signs that say artisan boulanger (but that doesn't guarantee they are all good--some people are just bad bakers). K has a goooood system--follow the crowd and follow your nose.
