The best sushi I have had here in the Rogue Valley, (so far) is at Tin Tin Buffet. It is an all-you-can-eat buffet style restaurant, but they do have a sushi chef on site, and the sushi is always fresh. You can get all you can eat including sushi for about $10. Very good for the price.
For France, I would say Mitchi in rue Ste Anne.
However my best sushi restaurants are in Japan, of course.
There was this sushi bar at 100yen (~$1) a plate in Shibuya. WWhile not the best you can get in Japan (but still a no contexst to anything I’ve found so far in France), quite unbeatable regarding the price. Then there was other one in greater Tokyo where some friends took me to (can’t remembrer the name nor the place unfortunately) where I ate o-toro… *sigh*. Something you’ve got to do at least once in your life. Surely, the price may appear completely indecent (20.000 Yen for the menu, the o-toro by itself being at 3.000 Yen (~$300), but then, it’s a taste you’ll never forget…
Generally, I prefer the “All-You-Can-Eat” Japanese Restaurants, which proliferate my city. Prices thereby are mostly/mainly more competitive than most above average restaurants! As well as, allowing for frequent visits!For one chain, they offer two menu choices for all you can eat: one menu has everything on it, and if you’re not starving or tastebud neutral, choose the lesser menu and be thrilled! Around $20 for the former, around $15 for the latter. And some chains discount down to $12 after 9PM !Yeah, we go “often” after 9PM !
PS: WHOLE table must choose the one menu or the other:
no mixing allowed! Since they can’t control/monitor abuse!
