Having lived in Greece and traveled extensively throughout the Middle East, I've had my share of authentic Gyros and Shawarmas.
That said, Greek Wraps definitely delivered authenticity in my experience. I'd like to see the price a little lower than $7 for a 7'' Gyro if I were to give Greek Wraps 5-stars, but I'm content to give them 4 stars for a great-tasting Gyro which was loaded with meat. The service and cleanliness of the order at-the-counter then sit style restaurant was solid.
