Tokyo restaurant culture questions

[mrsgodfrey]

Hello,
Traveling to Tokyo for the first time in mid October and have a couple of questions:

Looking through the boards, there is a lot of good info that dates back several years. Do restaurants in Tokyo tend to have a long shelf life?

Also, do you typically need reservations in Tokyo, or can you wander in? There are only two of us.

Of places that require a reservation, what would you recommend? Willing to go out of my way for something great.

Thank you for your time!

Lauren

Yes, restaurants tend to be around for awhile. Most of the info here going back a few years should still be relevant...Popular places should be booked in advance like anywhere else...You need to be specific with requests regarding location and type of food you are interested in.
