I've been to a conveyor belt sushi restaurant in America but that didn't stop this experience from being a lot of fun. If you've never seen or heard of conveyor belt sushi it works like this:
Step 1: You sit in a booth or at the sushi bar
Step 2: Sushi goes by you on a conveyor belt. You take the sushi you want to eat.
Step 3: Prices are determined by the color of the plate. For example the sushi in the picture is on a yellow rimmed plate which cost 100 yen. If there was a red rim it would have cost 150 yen.
Step 4: You pay for the amount of plates you ate.
The experience of conveyor belt sushi (also called "100 yen sushi" or "train sushi") is a lot of fun but I would say it isn't the tastiest sushi. I definitely prefer eating at a small sushi restaurant where the food is prepared when you order it (or whatever the sushi chef makes in my case since I can't speak a word of Japanese).
