Festa di San Gennaro (New York, USA)

Festa di San Gennaro packs 11 days of Neapolitan heritage into New York's Little Italy, since 1926 drawing over 1 million attendees to devour 500,000 sausage-and-pepper sandwiches. Cannoli-eating contests and Mulberry Street's neon glow highlight the celebrations, offering a taste of Italy in the Big Apple. It is cheaper than the typical street festival, with most food items under $8, and its 11-day duration is 3 days longer than #8 Feria de Abril. A quantified edge: the festival's 97-year history makes it the second-oldest in the U.S., behind only Philadelphia's Mummers Parade. The economic boost for local businesses exceeds $30 million, 25% higher than the average block party.
