Food in Germany is highly regional. You can have Kebab everywhere. The Sauerkraut beer and pretzels thing is mostly just Bavaria in the south. At the north sea and Baltic sea you got lots of fish naturally. In Hamburg you have Croques, Aalsuppe and further north Lapskaus. In the southern neighbor state to Bavaria you have Spätzle. And so on.

The beer also changes depending on region. Weißbier in the south and more mild beer in general down there. The north prefers beer with stronger taste that is more bitter generally.

There are few German foods which are generally accepted in all regions. Currywurst is one I'd say. Maybe grill Hähnchen as well although in the eat it'll be called Broiler while in the north noone has ever heard that word. Bratkartoffeln might also be pretty universal although ingredients probably differ. Egg or no egg, pickles or not.

Tldr German food is very different depending on region.
