We tried this place one lunchtime on a Berlin trip and promptly squeezed in as many visits as…read morepossible. I used to live in Japan and am resigned to eating random quality sushi in Europe, but this is best I've tried in a long time!
True, the chefs are not Japanese, but they make a big effort in food preparation and presentation. The rice is good quality and delicately flavored, the nori is crispy. The menu has a nice assortment of white fish like hamachi and tai and is a mix of traditional pieces and fried/cheese rolls that are popular in Europe. They even flambé the eel and other fish in true Japanese yaki style.
The setting is lovely, it's a converted alcove beneath the S-bahn, directly off the SW corner of Savignyplatz. They do things Japanese style here: take a seat at the bar and order directly from the chef! They will carefully prepare each plate fresh, rather than leave it on the little boats. Our miso soup was a little sweet, but tasty, with tofu and wakame. Plates are served with two nigiri pieces, like in Japan. The portions are very generous, the fish is carefully cut. At 3e/plate on the lunch deal (and Sunday eves), this is incredible value. I'll be coming straight back next time I'm in Berlin!
