Sushi-Tsune is my favorite Sushi restaurant. It's chain store and 25 of them are in Tokyo.
You can get hot roasted tea for free and in the case, you spend under 5000 yen. When you enjoy alcohol with dishes, you spend over 5000 yen.(about $50)
You can see how Sushi made by chefs.
My best sushi restaurant is amateur sushi.
It’s kind of high end sushi restaurant in Japan. I always pay 20,000JPY per person at night (without beverages). The chef is one of the best.
