Kebabs (or, as we usually spell it here in the States, kabobs) aren't wildly common here, so anything you'll find isn't going to fit some common perception of a kabob. That said, the ones I've had have been tasty, even if they've varied wildly. On the other hand, Boxer says that they're large chunks of meat over here, which raises the question of what they're like over there.

Oh, I see. The Wikipedia article on kebabs is actually very useful. To reiterate, what you call kebabs we call gyros or (much less commonly) shwarma. What we call kabobs you call shish kebabs, which is certainly a term we're aware of here, and would be a synonym.
