No I don't think it was a date as in just the two of them, as it was some sort of pre-Golden Globes Awards dinner for nominees, held at the restaurant. So lots of nominees and celebs there, for a big party. So they could just be friends. He seems to make friends everywhere he goes, whoever he works with!
Ah fame is a weird thing isn't it? So much scrutiny and speculation, and living life under a microscope. And having to repeat yourself to the press and fans, hundreds of times, saying the same things over and over again...If it were me, it would drive me absolutely potty - I think he does really well managing to stay polite and gracious. Must be difficult sometimes. I'd just die of self-consciousness, knowing my every move might end up being shared on youtube!
Anyway, if I met him in real life, as much as I fantasise about him, I think I would have to switch that off and just keep it very brief and polite - "Hello Benedict, I love your work, could I please have a picture taken with you? Thank you so much, good luck with the award/film/play/whatever." Just like the other thousands of fans he has to deal with I suppose!
See Benedict? If you're reading this, we're not that scary and are quite harmless really.
