it was a hot day when i went and i was surprised at how warm the place was. i wasn't sweating, but it could've been more comfortable.
i had the ninja and the big katuna. the ninja tastes a bit like a deconstructed spicy salmon roll (which isn't necessarily bad). the big katuna is more traditional poke. both were fresh and tasty, imho.
the large bowl is wider but also shallower. to my eyes, the regular and the large were not significantly different in size. however, i don't think either size would be enough for an adult. as such, i'd concur with the other yelpers who've complained about a lack of value.
the place is clean and nicely decorated. the servers are helpful.
to be honest, the thought of a bigger/cheaper bowl of chirashi does make me reconsider coming again. however, i think poke is sufficiently different and big tuna is the only place i know that does it. i'll be trying them again.
