5 stars for their omakase sushi - my favorite is their toro... at times they have run out when I have asked for seconds so I've learned to order multiple at a time. Make reservations, especially on the weekends, a day in advance. I love the casual atmosphere and they also have the usual non-sushi Japanese comfort food as well.
This by far has been my most favorite sushi restaurant I've found in the bay area. No fuss, no muss. I make the 1.5 hr RT commute without hesitation!
