Ever wondered why supermarket sushi tastes so unsushi-like? Wonder no more. It's not just about the rice which retrogrades under refrigeration. Yikes! It's being made by robots...
On a more humanistic note.
I've eaten sushi ( I actually prefer sashimi) in some of the best places in NYC but by far and away the best sushi and sashimi I have ever eaten, was at Ike Sushi in Los Angeles. And compared to NY, the prices are cheap. My friend and I ate for almost two hours and paid about 100 bucks sans tip. It's a tiny little place in a shopping mall and has a decor reminiscent of the luncheonette I worked in as a teenager.
Ike-san is a master.
The fish smells and sparkles like the sea. Google Ike Sushi if you think I'm being hyperbolic. I'm sure there are others quite as good, but this was the best I've had. And Ike-san is consistent. My friend has been eating there happily for 16 years.
