(My favorites were Italian Pistachio and Nutella.)
Each macron is $2. A box of 5 is $10. But don't kid yourself. Go for the box of 10. They are that good and you will want to taste all. And since flavors change daily, you will want/need to go back several time.
The pop-up shop will be open till the end of March, when Vendôme will open in 1 Brooklyn Bridge Park.
