If you are in Japan, make sure you visit a kaiten sushi restaurant. This one in Kyoto was great fun. Even for vegan or non-fish, there is plenty to order and it's cheap and good. First you need to get a ticket at the entrance. Select the big button, then press the number of adults and the number of children. Then you have to choose if you want to sit at a table of have seats at the bar. Mostly you have to wait a little after you've got your ticket. When seated, you can pick a plate from the conveyor belt or order some at your screen. The ones you ordered will appear on an extra plate which has your colour on it. We had a real great time at this restaurant. The service is good aswel.

This place takes sushi to a fun and practical level, while still maintaining an eye for quality. After a 35 to 45 minutes of waiting, you are seated at a table next to a carrier belt, on which sushi platters pass by. You've seen that before. Probably you didn't have the tablet on which custom orders (sushi, miso soup, drinks, desserts, ....) can be made, which shortly after arrive (announced!) on a platter with a distinct table color code. It's fun, practical, good food at a cheap price. And fantastic service. Give it a try!
