Passage 53 is a two-star Michelin restaurant in Paris, and we honestly don't eat at many places in Paris with that many stars. Too often the food is too rich, too expensive, and takes up too much of your precious time that you could otherwise spend stuffing croissants in your mouth.
But if you are looking for a high end experience without all the stuffiness, this is the place for it. Passage 53 is in one of those ridiculously cute covered passages that Paris has. The food is excellent and not as heavy as you might expect from a place like this, and it's worth a special occasion splurge.
