Best place to get Peking duck by yourself?

First, yes, I am aware of how sad and pathetic this request is.

I've run into some issues with Peking duck.

1) The good places require at least two people to order a duck. While some technically allow it, they seem to really frown upon a single person ordering a whole duck and constantly reiterate that they will not provide to go boxes.

2) There are places that serve to-go peking ducks, but they are TERRIBLE. Not even sure if it's duck, tastes more like pork.

Where can I go eat good (preferably great) Peking duck? Ideally in Tokyo, I know there are many good places in Yokohama.
