My wife, my son and I went to a sushi-go-round restaurant to eat sushi. The restaurant is a cheap one and they serve one sushi dish (usually two sushi on it) for 108 yen ($0.89 €0.79).
Three of us ate 29 dishes and bought 5 more dishes to take out for my daughter. I paid 3672 yen ($30.10 €27.00). If we eat those sushi at a common sushi restaurant, the price could be three times of those at sushi-go-round restaurants.
