The glass cases at Mannino's Bagel Bakery overflow with chewy, crusty, hand-rolled bagels. Bakers hew to tradition, celebrating New York cuisine—and elevating grab-n-go breakfasts—with old-fashioned recipes and time-tested techniques. Recent years, however, have folded some unexpected dishes into the Mannino portfolio. Today, customers enjoy rainbow-swirl bagels, as well as decorated cakes, paninis bursting with mac and cheese and prosciutto, and cookies and cannoli that make mouths water.
