Shinsen is one of the largest sushi manufacturers in Switzerland and primarily serves the retail trade. If you want to enjoy the Japanese delicacies fresh on the spot, it is best to reserve a table in the restaurant. Behind a glass pane the guests can watch the quick cooks at work. If the weather is fine, the terrace is open. Take-away possible. In Shinsen there are by far the best Mochi.
My tip: Edamame with Shichimi sea salt, Gyoza, Bento Tuna, Nasu Miso (fried eggplant with miso paste) and for dessert lychee + chocolate mochi
