Sushi

There are thousands of sushi restaurants in Tokyo and very hard to recommend one.
If you are planning to visit fishing industry part of Japan, sushi is usually cheaper and better there, so have sushi there instead of in expensive concrete jungle Tokyo.
The following are several sushi restaurants in Tokyo that I can recommend (or located close by).

Sushi Darihan
5-10min walk. 2 closest sushi restaurants are located next each other. Budget around 3000-5000yen. Closest sushi from the apt.

Tabelog Darihan

Tsukiji fish market sushi restaurants. 
All places should be pretty fresh and good. Choose the one with some queue.
Use Toei Oedo line to Tsukijishijo. You don't need to change train and takes only 20min to get there.

Midori Shushi
Shibuya's pretty good Sushi. Budget around 4000yen.
Never been but its super popular and make you wait for a few hours.

Belt convey sushi in Tokyo Sky Tree.
Should be English menu. Around 2000yen.

Numazuko

One of the popular belt-convey sushi in Shinjuku.
Of course Shinjku has lots of sushi especially around robot restaurants area (because of the rich hosts and hostess). This one is located west part of Shinjuku and quite cheap like 2000yen.

Sushi Iwa in Ginza

Very very popular sushi restaurants for travelers and not so expensive. Around 20000yen.
Need reservation in advance.

Sushi Isshin (The contract expired and not available anymore...)
One of my favorite sushi restaurants. It's an only membership sushi restaurant, so I need to go there with you (I have the membership). We need to book at least 2 months in advance so let me know if you want to go. Around 11000yen for 1 person.

Around 5000yen for 1 person,

The following are some top notch sushi restaurants in Tokyo. Dinner is crazy expensive (like 30000yen-50000yen) but lunch time is more decent.
Many places need to wait but no reservation required for the lunch time.
