I tried other AYCE sushi places, and i'm not really a sushi snob, as long as its pretty fresh and they make it, in front of you and as long as it tastes good -that good for me.
I've been here a few times, what I like about Island Sushi is that you get your sushi fix (if you are hungry) as well as Local Hawaiian specialtys like Poke, Mochiko and Garlic chicken, malasada, miso yaki fish, etc. Food is tasty and you will eat plenty. Try there special sushi like Candy Cane, Mauna Loa, Surf and Turf etc. Food is comes pretty quick and servers are pretty cool.
