Never heard of the first four. It is Kyubei, not Kyudey. Some of the best and most expensive sushi in town. Go there only if you are a real sushi foodie and can tell minute differences in quality and taste. Otherwise, many other places with better value for money. Skip Gonpachi, not really that good, and more of a place to take your foreign visitors. Kyushu Jangara is good, but it is rather low rent. Best to go at 4:00 AM to give consistency to the upchuck.
