Update - the first time I tried to go here (Senyuu) a few weeks ago I discovered it was closed on Sundays. The second time, a few days ago, the place was open, but smoking is allowed inside (a deal breaker for us) and no credit cards - also, the menu is all Japanese, no English spoken and I got the impression that foreigners weren't exactly welcome with open arms. After checking more local reviews, we decided we weren't missing anything here.

Two other reviews from the past week:

1. Sushi Takase near Yoyogi Station (or a long walk from Times Sq/Takashimaya). Highly praised by locals, the only high scores (near 4.0) I found for sushi on Tablelog. There is an online review in English by the website Gurunavi, but their information is almost totally wrong including the pricing.

The restaurant is beautiful and not busy, but reservations are required. No English spoken at all, no English menu. The only real option for non-Japanese speakers is the very well priced Y3500 omakase with 10 pieces of delicious sushi. We went on a Sunday, so his supply was somewhat limited, but if you go on a weeknight or Saturday, there should be more choices.

We didn't want the omakase, but after a few tries of asking for specific fish in Japanese and getting a 'not available', we decided to just do the omakase rather than sit there doing sushi bingo for an hour. After the omakase, I was able to order a few more pieces and had a nice filling dinner for under US40 all-in. A la carte sushi is around Y300 per piece for good quality fish in a very quiet, luxurious setting.

2. Katsu Seibu Shibuya

Here is a reason I will never trust Yelp again in Japan....mostly reviews by ignorant westerners who think good sushi (or Katsu or anything for that matter) comes from a Chinese owned buffet or food-court Japanese restaurant. The reviews of this restaurant ("best sushi I ever had!", "the most delicious sushi ever!", "the best sushi in Tokyo!") should have been a tip-off, however, desperate for something open late and buoyed by the sheer number of reviews, we decided to give it a try. For conveyer belt sushi (actually made to order and delivered via the quick-slide trays), it wasn't what I would call terrible - if you need a quick, cheap sushi fix, the place is popular and has lots of options, but not what I would consider high quality or very fresh. This should not be your primary go-to place for lower price sushi in Tokyo, but if you want a quick, late evening sushi fix with better-than-USA quality at cheaper-than-USA prices, it could be a good option to try.
