Kaiten-zushi, also known as conveyor belt sushi, is a popular inexpensive date night in Japan. And it's not really that unusual to see them in big cities in the US too. There have been places serving these inexpensive little bites of sushi in Los Angeles, anyway, since the 1970s.  However, just as there are rules for eating sushi, there are specific rules for eating at a kaiten-sushi establishment. These rules come from a Japanese site, but are pretty much universal. Your date is watching, and judging, you on your form. Commit these to memory.
