LOL! I asked the same question before our trip in February. It is just like the Gyro and very tatsy. I got the Chicken and Lamb platter and next time, I will just get the lamb minus the CousCous and extra Tabuleh. YUM!
I agree with the person that said the Gyros are a mixture of beef and lamb ground, pressed, then sliced. It's how I've always had it. I don't like lamb any other way.
