must eat Sushi resteraunts in Tokyo area

I'll be in japan for a week in may and I'll be staying in khaosan ninja hostel. I was wondering if there was some must of sushi places in tokyo cheap and expensive. I was searching through sites/forums and there was so many I didn't know where to start. I would just like recommendations and even other type of resteraunts is good. Also if there is any good places by the place I'm staying that would be much appreciated.

Thanks in advance

Tsukiji market..all are good

IMHO, nearly all the kaitenzushi (sushi train) in Ueno/Akihabara are good too and cheaper (high competition). There isn't a lot of difference in freshness since the market is not that far away so you'd probably do just as well there.

If Tsukiji is on your list of sights to see, you can easily kill two birds with one stone by eating sushi there. If you prefer another dish, then the Kaisendon (seafood bowl) places right next to Tsukiji market's entrance (the crowded area where all the people are shopping) are also good and cheap to boot.

CNN posted a story about a Michelin Guide 3 (or was it 4) star sushi place a couple weeks back you can check out if you have the cash.

I might have blogged a couple more on my site if you've time to read. http://metropolitansushi.com/blog
