A crepe is a thin pancake made from flour, eggs, and milk. It's often served with sweet fillings like Nutella or fruit.
You'll usually find crepes at French restaurants or cafes, but they're also popular as street food in some parts of Europe. Sometimes people serve savory fillings, like ham or cheese, inside the crepe, making it more like a meal than a dessert. If you see a sign saying "pancakes" but the menu has options for different sweet and savory toppings, it's probably offering crepes instead.
