I've been here a few times. I'm teetering between "Yay! I'm a fan." and "A-OK.". Why? The fish is fresh. The staff are nice. Its a bit pricey for the portion sizes. That said, they are at times generous depending on what you're ordering. They have a wicked cool grill squid dish that I tried once and really liked. You kind of have to study the menu to figure out the trick to what to order as ordering a particular combo feels like a better value deal than another. I tried substitution once - I asked for no rice with my sashimi - instead please a side of salad. They brought me a chopped up sashimi salad (I could have cried since all I wanted was those big chunks of sashimi - but not one to waste/complain, I ate it and paid for it). So substitutions - not so sure there whether it translates well.
Oh and I love their fried banana. Their tempura is good. Keeps me coming back for more. Like I said, a good place but you might need a map to navigate best cost/food ratio.
