Ted is gone for a little while before Sherlock gets a text. He's clearly managed to track down the café, in which there is apparently a Costa Coffee, with a wide selection of drinks (including more healthy options, like juice), freshly baked goods, packed sandwiches...

What would you guys like? They've got so much stuff.

Then there's a picture of the menu. Ted was this close to just buying a bunch of different stuff to bring back, but then sanity thankfully took hold of him.
