This chain specializes in shio ramen, a remarkably clear and pure broth with a salt base. A bowl of Afuri shio ramen with thin noodles and bitter greens will make you rethink how delicate and refined ramen can be. My first visit was in Ebisu, Tokyo and knocked my socks off. I was happy to discover their first US location on a recent trip to Portland– a much fancier interior, a much busier menu, but still some damn tasty ramen.
