$4 buys a portion of Greek fries generous enough to call a meal at the Souvlaki GR truck. Potatoes—skin-on and hand-cut to medium thickness—come delivered in a wax bag, piping hot out of the fryer, and seasoned with oregano, salt, and pepper. Then, the crowning touch: a massive helping of crumbled feta cheese. There's almost enough feta to cover every fry; the cheese softens against the crisp, crunchy, browned surface of the fries. Finish a bag, and you won't need to eat until dinner rolls around. But perhaps it's best to split the fries with a friend so you can save room for the (fry-stuffed) Pita Souvlaki or Bifteki Sandwich.
