OMG, if this is supposed to be Berlin's number 1 Sushi restaurant, then do yourself a favor and do not eat sushi whilst in Berlin. This place does not even look like a Japanese restaurant. Let us start with the staff, who truly make you feel like you are not welcome the minute you walk in, actually they are rude, and definitely not Japanese. The service was so slow from the beginning, I had time to take a nap before the waitress showed up. When the waitress finally showed up, she was so annoyed that we actually had questions that we hurried so that we would not bother her any longer. Then a second waitress shows up that was even more annoyed that we were there. Getting a bottle of wine took forever, and I do mean forever, which arrived just before the food. The food itself was "just" ok. They are trying far too hard to be a modern creative Japanese restaurant as opposed to providing quality. The sushi itself looked like (and tasted) like it was put together in a Bavarian restaurant, it just did not have the look that the sushi should have when there is actual care taken to present food the way it should be. To be honest there were issues with this place from the very beginning to the end, even getting the bill done properly was an issue. Do yourself a favor, avoid this place.
