Gyros are traditionally served with lettuce and tomato in my experience. I am also used to gyros made with fresh cooked meat directly off a spit. I think they just thaw some frozen meat here. It's the only place that sells them here so there's nothing for comparison.
Food is a whole different experience for me out here (about two hours outside of Chicago). As you can tell from my posts, I can't even get common foods and spices at our local WalMart (only grocery store besides Aldi). The town doesn't support a Farmer's Market and the more organic, higher quality supermarket closed right around the time I moved here (three years ago).
