The big trend in NYC has been these boutique type places that sell assorted flavored Macarons. While they are wonderful they are very expensive and the trip into the city makes it more pricey and just not worth it. I came across a great little shop in Little Falls called Asalt &Buttery. They had the same amazing flavors (Rose, salted caramel, pistachio, raspberry and others). I thought they were very good and pretty comparable to the ones I bought in the city. While they are still a little pricey they were way cheaper than New York City.
