Time Out says
Forget rails, here your sushi is delivered by boat
No one is denying that sushi train is a bit of a gimmick, but it's fun, and people like it. Not content with the rail-based food delivery system, the crew from White Mojo have decided to take your sushi experience to the high seas (or at least the low canals) by creating Sushi Boto, a boat-based delivery system. Your ships, nigiri and sashimi are delivered by little boats running along a canal. While you're there you can also drink sake, and for the ravenous, sign up for a ten-step sushi degustation that gets saltier and more savoury with each dish. If you spend over $30 you also get a coin to put into the imported vending machines stocked with Chanel and Tom Ford lipsticks and dining vouchers.
