This place is great and never a disappointment. The staff are courteous and attentive walking you through the Ingredients and options should you have any questions.
There is 2 bowl size options. 1 regular/small and the other a large. A couple can share 1 large and be satisfied easily. If you wanted to do your own thing then get a regular/small. You'll be stuffed either way.
The fish is tasty, fresh and well kept. The place is spotless behind the counter which is key when serving a lot of raw meats(fish in this case).
I have never been to Hawaii but from what I hear this place gets the look and taste pretty spot on. Save your money on a flight ticket and come try out this location.
