You could be in the middle of butt#$@& nowhere in Deutschland, and some random Döner joint would probably be right around the corner. You North Americans will be intrigued to know that there are more places to get Döner in this country than McDonalds locations! (it seems like that, anyway) The bottom line is, Germans cannot get enough of this fast food. It's cheap, it's tasty, and of all the places I've been to so far, it's always been decently good.
What the eff is a Döner?! Well, all I know is that in Toronto, we call 'em "Shawarma" or "Kebab." And none of the "Shawarma" or "Kebab" I've had in Toronto have ever come close to the Döner I've had in Deutschland. A Döner is usually no more than 3-4 EUR, filled with shaved meats from a rotating spit (i.e. chicken), topped with veggies such as tomatoes, lettuce, cabbage and red onions, and served in a pita-like flatbread. Some Döner joints will toast your Döner in a sandwich press thingy, resulting in a Döner that is beautifully textured and crisp on the outside. Miam miam.
Having tried a Döner in Berlin, Hamburg, Münster and in Braunschweig, I've come to believe that wherever you go in Deutschland, a decent Döner can be had. Of course, variations do exist. For example, some places offer garlic sauce or hot sauce as options. If you've never tried a Döner before, here are my 3 recommendations: 1. Make sure your Döner is toasted (preferably in a sandwich press thingy) 2. Ditch the hot sauce (if this is your first time trying it, you wanna try it in its most original form, don't you?) 3. Wash your Döner down with a bottle of Ayran (best... sheit... ever. seriously though.)
