Went there since it is very close to the Imperial hotel.
Very crowded but after a short way we got a table. Friendly waitress who spoke some English, but with the "English" menu and looking at the neighboring table you have a wonderful choice.
We had Sushi, Sashimi and Tempura, all tasted great. Portions are small so we re-ordered the dishes we liked best. Good Kirin beer on tap.
No credit cards are accepted but due to their reasonable prices we just made it with the cash on hand.
Great place for good food at very reasonable prices, especially in such an expensive city like Tokyo !
