It's the sushi restaurants where little plates of sushi go around the whole place on a conveyor belt, hence the name. I think somewhere in the world, there's an outdoor one.
I went to one recently, and it was pretty good. It was a small store, so the sushi wouldn't go dry and stale before it even reached your table.
A suggestion would be to go at dinnertime, as there are more people. It means that the food on the conveyor belt is being taken quicker, and the sushi is fresher.
Not many conveyor belt sushi places offer AYCE (All You Can Eat). Instead, at most places, you pay for each dish (and a dish usually has 2-4 pieces). Depending on the colour of the dish, the prices differ.
It is an enjoyable experience.
