I haven't, but I do take issue with the whole conveyor belt concept. It promotes waste when overfishing is a real problem on this planet. And the patron is paying for all that uneaten sushi that has a limited conveyor belt life when the conveyor belt is properly monitored and they don't pull the maguro and resource it into a spicy tuna roll. Not saying this place would do that, but some do.
been there once. meh. Not bad but I've never liked the conveyer belt places even in Japan. The sign outside says revolving sushi that my mind keeps morphing into revolting sushi (unfair). Irashi a block away on Kneeland is better.
