Osovanokouga is a small soba restaurant in Tokyo that serves cold and hot soba. The uni soba comes with sea urchin piled on the noodles in roughly a one-to-one ratio, and there is also shrimp tempura soba and sudachi soba. The space is very small with seats packed close together, and a line forms behind the opening rush. The uni soba is on the higher end of the price range.
