Tokyo Restaurant & Sushi Bar

We emailed them and was able to get a lunch spot.

Reservations do need to be made by phone. I spoke to a staff member who was just fine with English, and emailed me afterwards to confirm the reservation. Edit: I should also mention that the hours for calling to make reservations are not the same as the hours that they're open and serving customers, and are very late night if you're in the USA. Double check on their website!

Yes. You can use it.

It is not barrier-free (laugh)

I think that reservation by phone is difficult because it is popular here. Existing customers make the next reservation at the time of use.

Reservations can be made up to 2 months in advance. I recommend calling as soon as you can in that window, as the available times filled up quickly in my experience!

Den offers a set of courses selected by the chef rather than a full menu, so if you need to stay vegetarian they may not be the best fit. I would recommend calling them to ask if they can accomodate a vegetarian diet.

You can call them at 1 +81-3-6455-5433 between 12pm and 5pm from Monday to Saturday to make reservations. More details on their website.
