2nd time wasn't the charm for Kahuna.
On this visit I ordered the large Big Island Classic on a bed of greens. The portion is, again, HUGE. (but for nearly $14, it should be.)
I wasn't a big fan of this bowl. The tuna was fine, but not as good as my first visit. The rest of the bowl felt surprisingly heavy - from the sauce to the cucumbers to the hijiki. The macadamia nuts provided a nice crunch, but otherwise the whole thing felt a bit disjointed. (I also added by own avocado at home).
I didn't actually finish the whole thing, which is a rarity for me. If I go back I think I'll stick with making my own combination.
