While I think the typical Döner price reflects inflation, as when the German Mark was converted to the Euro, a Döner cost 3 Euros or 3.30 Euros with cheese, and now we're at 7 Euros or 7.50 Euros. Although it's worth noting that Döner Kebab in places like Berlin is relatively cheaper.
Wen Dönerpreisbremse? 👀
Btw, I moved from eating kebap to shawarma. There are way too many kebap places where I live and I think they know we Germans don't care about quality too much when it comes to kebap. As long as it's still affordable! lol
No seriously. We have multiple kebap places next to each other, lol
