My wife and I went on the Magic in January, and they only had the beef shwarma going and were prepping for adding the chicken rotisserie.
That said, it was awesome. I admit that I ruined my appetite for dinner a couple of times. But I remember they had several base spreads to put in your pita that included hummus, taziki, baba ganoush and some hot red spicy sauces (can't recall what they were called). Then the meat goes in, and you pick a topping, which could be simply be diced tomato or onions, or a Kachumber salad (no, that's not a typo), and more.
It's excellent. Definitely my favorite counter dining option on the ship, hands-down.
