I think the name is Chinese, but the dishes look Japanese. I am no expert though. Did you eat with chop sticks?
I was once taken to a Korean restaurant and the waitress asked if we needed forks. Then the pastor that invited me says to her, No, everyone here is eating with chop sticks or they won't eat. I wasn't sure if he was joking.
So I did remember my mom showing me how to use them when I was a child. It was a little difficult, but I got to eat. I always like to use chop sticks at Asian restaurants now days.
