I really enjoyed the sushi I had at Akai Hana (Red Flower in English I think). I had the spicy tuna roll on special for happy hour and also got the Phoenix roll (Eel, smoked salmon, cucumber, avocado, sweet egg). The spicy tuna came out quickly and was good. The Phoenix took a little longer, but I thought it was really tasty.
The staff was very nice and helpful with any questions I had. The water I had tasted... like water and was refreshing enough for me.
The place seems to have a lot of traditional Japanese dishes I don't always find at every Japanese restaurant I go to. Also, the majority of the staff were speaking... Japanese, which strangely seems rare from the places I have been to in the Valley.
I will definitely be back to check some of the other stuff on their menu (like their sukiyaki that is for a minimum of 2 people, that sounds like fun).
