No proper Döners in Helsinki

Hi, I’ve been living here for about 3 years. Though, I have tried most kebabs in Helsinki, I haven’t came across a place where they have the meat spinning on a stick, like a real döner place in Germany, Turkey, etc. I’m from the EU and travelled around most of it, and wherever I went, the kebabs were served from on a big piece of meat, which was spinning and they cut it right into the pitas/tortillas. It made the kebabs feel fresh, tasty and authentic (and affordable).

I couldn’t figure it out myself so I’m asking you; Is there any reason why that’s not a thing here?
