But it was raining.
So instead we went to see Mission Impossible: The Ghost Protocol at Sony Centre. (We enjoyed it although I was annoyed the sub-plot pertaining to Ethan's wife: it made absolutely no sense.) Then dinner at Vapiano, a quick and rainy look at the Potsdamer Platz Weihnachtsmarkt and home again.
(I like the architecture of Sony Centre very much: a great use of what was a bombed out and empty space and I am not much of a one for Weihnachtsmarkts unless it's snowing and they look cute: I don't eat many traditional, pig-based German foods, I don't enjoy crowds, and my alcohol tastes run more to the red wine and less to the anise/cardamom scented Glühwein. So I didn't really feel deprived.)
