First up was Francois Payard, which is the originator of the amazingness of Macaron Day. I got a chocolate macaron and it was so, so awesome. Perfect texture, flavor, everything.

I would have eaten about a zillion more. Fortunately, there were two more stops on my walk.
Next up was Mille-Feuille Bakery Cafe. They weren't offering chocolate macarons when I was there, only caramel. But even the caramel was delightful, despite its handicap of not being chocolate. They also had other appealing-looking chocolate baked goods on display. I would go back.
Third stop was bisous, ciao, which you know is going to be good because they only sell macarons. They had more than a dozen flavors, though not all were available for the free sample.
The one I got was blood orange with a dark chocolate cream in the middle. Phenomenal. So flavorful. I would go back here, too, and try more of their many flavors, like the peppermint dark chocolate one, which sounds like it's designed for me.
BOTTOM LINE: Macarons are expensive. So it's really nice to have a day when you can eat them for free.
