1. Buy your baguette at Village Baking & Co
Their bread and viennoiseries are among the best I have ever eaten, even in France! Let yourself be tempted: take a few croissants (I strongly recommend their ham & cheese croissant!) to eat right away and buy a baguette.
Then buy President butter and “real” ham at Whole Foods, make yourself a Jambon-beurre, take a blanket and go for a picnic in your local park.
