Crepes are basically synonymous with France, but not, in fact, with Paris: They’re famously a product of the Bretagne (Brittany) region, several hundred miles west. In fact, historically there’s  been a cluster of top crepe places near the Gare Montparnasse — because that’s the train station that serves Brittany. The Bretons who came to Paris first arrived at that train station, and then to that neighborhood — and they brought their crepes with them.
