I've been to both Haruki's, both Shogun's, and Seven Moons. Haruki is the best of these, with providence having a hipper atmosphere, and maybe slightly better quality in Cranston. I like the Shogun in Narragansett more than the Cranston one, mainly becuase it looks and feels nicer. Seven Moons has been a little disappointing, mainly because of the variability of the sushi. My opinion so far.
I have not been to Sakura, 10, Sea Shai in Middletown. What do people think of these places, and are there other places worth pursuing? I realize that we are not talking about high-end New York or Boston sushi. I wish there was a place in East Greenwich.
