The most coveted French macaron boutique in town opened today, Ladurée on Madison Avenue. Everyone above 59th Street is there in line, while everyone below 59th Street is buzzing about their downtown expansion plans, which the rep confirms to Grub Street is happening ("We are looking at downtown locations, yes"). The first people to ever buy a Ladurée macaron in New York? "A family from across the street, who bought sooo many!" says the rep. Move over, cupcake, it's macaron's moment.
