The savory version isn't technically a crêpe at all in France — it's a galette, made with a completely different flour.
A crêpe is a thin pancake cooked in under a minute on a round hot griddle, then folded around a filling — Nutella and banana or ham, egg, and cheese are typical street versions. Vendors work from small stalls or vans, pouring the batter with a wooden rake and folding it to order for people walking past.
