I used to live in NYC and would frequent the original cart a lot, so coming here to try the store was a must. I went on a weekday, around 2pm - there was a lineup, but maybe for only 15-20 minutes.
Honestly, the cart is miles better than what they're serving at the store. But with that being said, the regular combo platter is a generous portion of chicken, gyro, rice and salad and you really can't go wrong. Even the small size can fill you up.
And, as always, the white sauce is where it's at.
