All you can eat in Tokyo

I searched and found that there are two All you can eat luxury sushi places.

1. Hina Sushi - Ginza
2. Tama Sushi - Ginza and Odaiba.

Can anyone tell me what the prices are?

Also does anyone know of any other places with all you can eat?

I remember seeing some being recommended on Cool Japan, except they never mentioned the name of the shops.

here are the prices for Tama Sushi

I must say I find it hard to reconcile the appearance of both "luxury" and "all you can eat" in the same sentence.

I think there are time limits for any all-you-can-eat places and they're not that long.

I've been to Hina Sushi and it's actually pretty good. Not super-high-end sushi, but better than kaiten-zushi also. I think it was around Y4200, so not especially cheap.

Time limits on all-you-can-eat places are usually 120 minutes, which I think isn't unreasonable. Here's a list of buffet restaurants in Tokyo: http://www.bento.com/r-buff.html

If you are able to read a little Japanese or have patience with trial and error or online translators, here is a site (all in Japanese) devoted to Tokyo Area all-you-can eat restaurants that I have always been fond of. Years ago it used to be more extensive, but I expect it was too much of a burden to keep it up. Poor Ikuko probably got too fat.

There aren't as many current reviews as there used to be, but the index is still useful, and will lead you to a page devoted to sushi places:

The pictures need no translation of course!
