Falafel has its roots in the Middle East, but it makes a perfect New York City street food. The fried chickpea dish—often served in a pita with such accoutrements as tahini, salad, hummus and hot sauce—is cheap, fast, filling and suitable for vegetarians. Nedal Chater, who helps run the legendary Mamoun's, believes the dish's appeal lies in its speedy preparation and affordability. "It's cheap—that's the draw," fala-sophizes the son of founder Mamoun. "And then it tastes good." He adds, "We know that people don't like to wait. I hate when I go into a restaurant and [employees] are socializing. No! We hustle in our store." It's true—falafel purveyors are famous for their swiftness.For those who'd like to taste what the fuss is about, we've taken the liberty of listing a few fantastic falafel traffickers, arranged by price from fal-awfully cheap to merely economical.Greenwich Village and East Village, ManhattanPrice of falafel sandwich: $3The original Greenwich Village location has been cranking out fast, cheap, crispy falafel sandwiches for 40 years, and it's open till 5am.
