"Rule #3 is a sushi law."
It should be an enforceable law. Sadly, a lot of people get the idea that sushi is that stuff at the wedding reception, so they never find their way to a sushi bar.
A pity. Then you get the "I ain't eatin' no raw fish" crowd. I just let them eat all the California Roll they want while I go for things they won't eat.
In reality, I'm a bigger sashimi fan than sushi fan anyhow.
