We've got them in St. Louis, although they are slightly different than the ones common in Europe. (as the places that serve them here are usually Bosnian instead of Turkish). They're served on somun or lepinja bread and use tzatziki sauce instead of the sweet white/spicy red sauce combo that's typical in Germany.
Here's the online menu for one of my favorite places: https://www.jspitaria.us/s/order (they also have a Berliner kebab, which is a little closer to the ones in Germany, but not quite the same).
