Eat sushi

I will take a backpack trip to Tokyo in September.
Today I started to look for any delicious sushi restaurants in Tokyo, so I can visit them.
After I read several articles and saw the photographs of sushi,
I decided to have dinner at a sushi restaurant which is nearby my house.
This sushi restaurant is a chain restaurant, and every disk has the same price, about 1 USD.
That's why I like to visit it.
I like sushi definitely, but visiting during the weekdays has never happened before.
I am looking forward to the trip.
Hope it comes soon.
