A mix of very good, very interesting, and just average. I think it might appeal more to the hardcore Japanese palettes with some of the more interesting sushi pieces-- they used a tiny shrimp we normally see dried as one style of sushi, it was more devoid of flavor than anything else.
Most of the rest was excellent and innovative, or at least interesting-- sockeye salmon is not the most common cut, and it has a different texture, while others like anchovy are more common at higher-end sushi places. Flavor wasn't up to the top places, but considering the price, it was in-line with expectations.
Only real miss was the smoked oyster. Some might love it, I was indifferent.
Service was authentic, tho, down to the Japanese staff and conversation that went on entirely in Japanese between Issei and the staff. Definitely a worthwhile experience!
