One of the great street foods in NYC is the Jamaican patty--in multiple forms. My preference is vegetable (and Christie's has an interesting contrast to some others in the city), but others like chicken and beef. There's also a good array of Jamaican entrees and cakes and drinks. This is a little triangle of a place on Flatbush, and there's often a line, but it moves rapidly. Prices are a little better than comparable places in Manhattan.
