Wonderful croissants aux chocolat et aux amandes (if you can get them). Sweet, flaky, soft, and delicious. Perfect with a cup of chocolat au lait chaud.
"You got very hungry when you did not eat enough in Paris because all the bakery shops had such good things in the windows and people ate outside at tables on the sidewalk so that you saw and smelled the food." -Ernest Hemingway, A Moveable Feast
Update 2012: Sadly, this boulangerie no longer exists. What a loss for the neighborhood!
