I would love to ask Motfiss about this, rather than talk about future series I'd love a talk dedicated to explaining this whole episode!!!

I don't think that's Speedy's. When John and Mycroft meet there at the end of ASiB, it looks pretty different to the restaurant where Sherlock and CAM meet. Smaller. Not so many tables. Different interior.

On a completely different note, when I watched the episode for the first time, I wasn't quite sure if this scene was actually happening, because it felt so very much like a dream sequence to me.

Same with me. It really has a dreamlike quality. I mean, Sherlock eating pasta!! But seriously, the whole timeline is weird. We basically do not know anything about what happened from the moment the paramedics turned up at Baker Street up to Christmas. 
 

Susi, I read your fanfic about the missing scenes between the shooting and 221 B.
When we additionally try to force the not-cantine scene in it with Sherlock in this ridiculous hospital not-pyjama eating pasta we need to make a knot in our brain to fit every silly thing in:
Putting the chair back, buying Clair-de-la lune perfume, meeting CAM, instructing John, preparing Marry's picture to appear on the facade of Leinster Gardens. And all this while seriously injured in a hospital not-pyjama with a wheel chair??????
Well, we have Billy to help?? Really?

I would also say it happend when he was in hospital for the second time. Mary should have become their "client" before Sherlock arranges the deal with CAM. Makes more sense to me.

I think it is improbable that he escaped from hospital twice.

I won't say that. It's Sherlock. And I don't think that he was watched all the time.
 

We can only guess and still we won't get anywhere with it...
Just as a theory:
Sherlock had apparently organised a lot of things, the chair, the perfume, the facade. Why not the meeting with CAM, too? It would also be efficient to organise everything at once.
And I imagine that at least Mrs. Hudson brought him a proper pyjama for his second stay at the hospital.
Sherlock wears this ridiculous not-pyjama in the not-canteen. You only get something like that when you are brought in on an emergency and you are not yet equipped with personal stuff, so possibly at the first stay right after Janine talked to him and he saw Mary in his mind and had another look at her.

Can you imagine Sherlock with a wheel chair and a not-pyjama and  morphine equipment wandering around London? Really? I can imagine him with a harpune, almost.
 

Yes, I think it was important for Sherlock to know how the relationship between John and Mary would turn out (which is not entirely clear until the end, but this is beside the point). 
I think he did not just target Magnussen because of Mary and John. Remember he loathed him even before he knew about the connection between Mary and CAM. He loathed him because he targeted people who were different, people like himself. 

I think he has several reasons for shooting him in the end:
- he is indeed a danger to Mary and by extension to John
- he targeted Mycroft via Sherlock
- he threatens to publish Sherlock's attempt to sell his brother's state secrets

That´s exactly why I think all that restaurant scene was just arranged by Sherlock to give CAM a wrong impression about him. Because there´s obviously something fake about it.
