Restaurant Myth

I talked to the chef at Urasawa (Hiro Urasawa) and he told me about an interesting story. He said a few of his customers told him of a sushi restaurant in LA that is supposed to be super high class and expensive. They say the restaurant charges over 500 dollars a person. It's supposed to be a small place that is very exclusive. But he said, people hear about it but he have never actually met anyone who have gone to the place. So, I guess it's a myth then. Anyone know about this place? He also added that his restaurant is one of the 3 restaurants from LA that make it in the top 50 ranks in USA (the others are Spago and another one I cant remember). Then, he had two thumbs up and smiled.
