We'd heard that Blé Sucré makes the best croissants in Paris; so, of course, we had to check it out. They were absolute magic heaven: a bit crackly on the outside, with moist, delicate wisps of buttery pastry on the inside. The chocolate croissant was equally amazing. We ate it outside with an espresso. Go on a weekday at lunchtime when there's virtually no line. Be prepared to wait during the weekends.
