Will be going to Japan in November. Unfortunately, I'm not going to Oita so will not go to the home town of seki saba. Can someone recommend a (traditional, preferably) sushi bar that carries seki saba in Tokyo that's fairly centrally located and are somewhat foreigner friendly? although i will try my best to communicate, my japanese is extremely limited. As I'm not on an expense account, a recommendation that's not scarily expensive (~100/pp) would be highly appreciated.
