$5.25 for a hot dog, $16.50 for burger, fries, and drink? Ouch! Instead, get your hand stamped, and step outside the Open for late lunch off a hot dog cart in Flushing Meadows Park for half the price. There are carts immediately outside the East Gate, or near the Unisphere out the South Gate. Or walk farther in the park toward the soccer fields, and you'll find a couple Ecuadorian and Peruvian snack carts for even less money.
