We went back to Ah Hai a few days ago after trying different sushi restaurants in the area. I think the big draw of non-luxury Sushi restaurants like this is Happy Hour. I've docked a star for a couple reasons.
Selection - Happy Hour menu is smaller than average. Would like to see more of the popular selections on there.
Quality - I will try to post a picture of the Rainbow roll we recently had. It was about half the size of most Rainbow rolls you can get. The color of the fish was dull. Not as bright and vibrant as you would like to see. The fish was really thin, not much there to get a taste of.
Value - The menu is expensive considering the product that is delivered. It's not a good value.
Overall the place is OK. They have slightly different Happy Hour times, so if you miss Happy Hour at one of your other places and really need a sushi fix, this place will suffice. In my opinion though, there are a lot of Sushi restaurants in the area in close proximity. To get the business you have to either provide a top product if you are going to charge a premium for it, or be what you are and provide cheap sushi for a cheap price.
