Awesome Tempura/Tendon (Tempura on rice) place in Tokyo. Long history, feel it even from the building, walls, tables and everythig. Perfect place to start liking Tempura/Tendon. Servis lunch only, so get there prior to 11:00 and yet you'd probably see some people already lined up. You've got to try it for once.
My rating: 5.0+ (Awesome!)
