Japanese traditional Izakaya. 5min. walk from Shibuya Hachiko-Exit. Food quality is quite high.
"The building is old traditional Japanese house, and buiIt 50years ago, therefore, it might be difficult first time to find the entrance as it looks like someone's residence, but,
inside is wide enough. Each section is based on as private room, so it would make yourself comfortable.""... by Kanno
