"Patisserie Chanson is a French bakery in Flatiron with a few rotating flavors of very good, very fancy soft serve. They have a black sesame kouign amann with yogurt pop rocks (in the past we’ve seen pistachio, and a strawberry one topped with basil, rhubarb, and sweet pieces of bread). There isn’t much signage or advertisement that they have soft serve, so you just have to ask." - Hannah Albertine
