My croque madame was nothing of the sort (cheese and ham on a crusty piece of bread with a fried egg perched atop) - too dry and without that cheesy béchamel goodness that makes a good croque.
The perceptive amongst you will note that I still award 3 stars, and that is because the frites are EXCELLENT and deserving of a UNESCO world heritage award. Plus, they're nice guys and it's open when most things around there are close (e.g., a cold Monday in January).
