Visited on Saturday, right after 5PM opening. As I did a few years ago, I sat at the sushi counter and asked master for 'omakase' for $50. He gladly accepted my request.
Omakase consisted of; nigiri sushi of master's choice and they are; salmon, hamachi, ikura, uni, red snapper, cucumber roll, unagi and my request of ika (squid). In addition, omakase came with a tempura appetizer, crab meat assortment, and grilled mackerel with salty flavor. I wanted to end the meal with ramen and this time I ordered miso ramen. It was excellent. The bill did not say ramen so I asked. The master said he put ramen as a part of omakase. What a treat!!
I ordered Katsudon to go since I drive a distance to go home. Later after I came back home, I ate Katsudon as a night snack. It was excellent.
As a native Japanese, I fully enjoyed Shinano, because it is one of few authentic Japanese cuisine in the area. I am not against Japanese restaurants owned by non-native but my experiences show the Japanese owned is always the best.
Japanese cuisine can be found everywhere these days but there are few true authentic ones as far as I know. If you adore a real (I mean a real) Japanese taste, try Shinano. You will be happy to visit and leave with a smile on your face.
