Kajika
Established in 1968, a 1-minute walk from Unazuki Onsen Station. Famous for 'kama-meshi' (pot rice cooked to order) and Toyama-style oden. Managed by three generations of the same family, it's the only dining spot in the hot spring town that stays open late.
Tabelog 3.44/159 reviews. 'A cozy, family-run establishment passed down through three generations. The oden broth is deeply flavorful and the kama-meshi crust is superb.' TripAdvisor also shows 25 positive reviews.
