On the advice of a friend I tried Niwa over Mye. What a mistake! The sashimi was rubber. Worse than the worst food court fish. And they could not customize a roll to exclude tempura bits because they make their dressing in huge vats versus making it fresh. I left after some very poor service and ridiculously disgusting food and went directly to Mye, which was pretty decent.
Avoid Niwa at all costs. It was the worst sushi I have ever had, and the staff were horrible.
