Authentic Chinese in Berlin? Yes. There are. Actually quite a few. The issue is: no matter how authentic they are, they still have to cater to the local taste. Therefore you will always find a somewhat mixed menu. A mix of authentic and “westernised” dishes. But that true for pretty much every country outside of China.
Da Jia Le is certainly one of the most authentic ones we have been so far. We decided to come here after we had read a few positive reviews. We were not disappointed. They claim to be specialised in Dongbei, which is a Northeastern China specialty Cuisine.
