A souvlaki is marinated cubed meat, usually pork, chicken or lamb and is cooked over a grill or charcoals on a skewer. It is served this way too, unless you order it in a pita. A gyro is made from a giant kebab of layered meats, such as chicken thighs or pork and is cooked over a rotisserie and shaved with a knife. It is served in a pita with tzatziki, onion, fries and some form of salad.
