Stayed at hotel near Midori and we almost went there every day to see if there's long line up. Since we have 2 children and they would not like to line up there for long time so we are disappointed few days in a row. There is no reservation at Midori. That's why you see long line up almost any time of the day. We finally went there one afternoon when they just open. It takes us 10 mins to get a table.
Waitress speaks well English. They do have English menu too. I ordered a special set cost 2100 yen. I think it is very good deal. Although it is not the best sushi I ever have ( I personally like restaurant around Tsukiji more) but you can't beat the price. It also include a miso soup, a crab meat salad and also a steam egg. I feel so full after it. Kids get egg sushi and cucumber roll and the size of the egg sushi is so big!
I think there is a reason why this restaurant is so popular (not just for tourist but mainly Japanese people too) because you really get more than the value.
