Keyzen is the perfect place in Copacabana for a Sushi Rodizio. In other words, eat all sushi, temaki, sashimi and yaki that you want for one fixed price! The restaurant is all in Japanese style and the attendance is good. You just order per round by checking the boxes on the paper and in no time you are served. As most of the Japanese rodizios, you will be charged for non-eaten sushi. Understandable, as making sushi is a time-consuming business. But don’t worry, you don’t have to hoard, you can always order another round of delicious Japanese food!
