"Like most of the Japanese chefs based in Europe, Jin's Takuya Watanabe is outsourcing his tuna from Spain.He said that even if the most fatty tuna cuts from Spain are not that great, the leanest part, akami is very good. He served akami sashimi with seaweed and soja sauce ""jam"", which was a perfect match. For me Jin is the best high end sushi-ya in Europe.(Together with Araki in London,which price level is at least double than Jin.)"
