I mostly have to agree with the sentiment here when it comes to Germany and Mexican restaurants – with one BIG exception: Berlin. Since a few years you will find authentic Mexican food at a handful of restaurants that are run by younger immigrants. The ones I know and recommend are El Cabron, Sabor a mi, and Taqueria El Oso. All of them are fantastic and I have it on good authority that they are authentic. I only been to Mexico once but the Tacos at El Oso are kissed by angeles mexicanos. At the other places you can also get dishes like Sopa, Tamales, Quesadillas, etc.
And if you’re looking for Californio food, head to Dolores. Very solid burritos und bowls since 2004.
Ja, tach auch… moooooooment mal!
