Authenticity: very authentic. Japanese owned business. The only place we repeatedly take my Japanese mother when she visits us from the Bay Area. Nuf said! This place is so special to me that I almost want to keep this gem to myself and not share! However, I want this place to always be here, so that means sharing the joy.
Food: sashimi combination at lunch. For dinner, I like the combination with sashimi, sushi, tekka maki, tempura, and grilled fish. On the specials menu, they have unagi donburi (BBQ eel bowl) that my daughter loves and is very spot on authentic down to the black lacquer box it's served in. BTW, this is how miso soup is actually supposed to taste people!! Most places here can't make it correctly.
Ambiance: decorated simply and with authenticity.
Service: friendly. Sometimes some dishes take longer than others but I don't care. Having this slice of Japan so close to me in Henderson is worth the wait!!
