If you happen to be staying, let’s say for a single night in Hamamatsu City, near the JR Station, I would suggest you visit Takasagotei Restaurant on the second floor of Hamamatsu Sago Terminal Hotel just right of the JR station south exit.
As a hotel izakaya since the 1970’s they are definitely above the run of the mill level of the fare usually delivered in business hotels.
They also have the great merit to offer a large range of Shizuoka sake out of their long drink menu, which warrant a visit by other Prefectures’ guests:
