Every summer, the Puerto Rican community of Loisaida -as they call the Lower East Side of Manhattan- throws a festival to celebrate its culture, its music, its theater and its food.  The Fest brings together a mixture of old residents of L.E.S, the survivors of ravaging waves of gentrification and change, and young, new transplants from the island looking for a place to feel at home in their new city.  Loisaida is that place.
