I've been to Kabuki a few times and have never been that impressed. The service is mediocre, the food is decent at best and the cocktails are nothing special. The ingredients seem semi fresh, but there are definitely way better places in the valley if you are looking for delicious sushi. My suggestions: Ra, Blue Wasabi or Squid Ink (depending on which part of the valley you are in).
If for some reason my review hasn't changed your mind from going and you find yourself at Kabuki DO NOT order the Sangria, you WILL BE disappointed. As for the food -- I guess there are worse places you could go.
