We ate at this Mexican restaurant last night in Oberkassel, a neighborhood in Duesseldorf located across the Rhine. I was pleasantly surprised how authentic the food was. The chips and salsa was very tasty. We ordered guacamole for the chips and even that was delicious. I ordered a fish burrito which was sehr lecker! ('very delicious' auf Deutsch) The fish was a white, flaky variety grilled to perfection. It contained black bleans and a delicious creamy sauce poured over the flour tortilla. Even their margaritas were good! They were made exactly the same way they're made in the US and Mexico. I mention this because I have ordered margaritas at other bars in Germany and they never come out right. For example, one time the waitress brought the margarita and it was green, no ice, in a martini glass. It looked like a green cosmopolitan and didn't taste anything like a margarita. So the ones made at Zapata's are authentic.
I now have a new, favorite restaurant. If you're ever in Duesseldorf and you're missing some good Mexican food, go to Zapata.
