In addition to our guide for the 8 best macaron shops in New York City, you can use this handy map from Gothamist that shows where they are free on Macaron Day, tomorrow March 20th. Participating shops will donate a portion of the proceeds to City Harvest in this annual festival started by Francois Payard in 2010. A few of our favorites from our guide will be offering free macarons today including Payard, Macaron Parlor, Bisous Chiao, Macaron Cafe, and Bouchon Bakery.

A full list of shops is available here. Read more about the city’s macaron shops in our guide of our 8 favorite macaron shops.
