This Williamsburg bakery has been known for its pastries—with cases full of cannolis, colorful marzipan, croissants and cheesecake—for more than three decades. And locals swear by the house-made gelato, its rainbow of seasonal flavors ranging from pistachio to pineapple. The old-school atmosphere, and the crowd to match, brings patrons back to what the neighborhood was like, pre-hipster.
