Yesterday evening, I spent some colorful time at Google Berlin. The offices in Berlin are situated in a very fancy old block of apartments on Unten der Linden. Once you are there you should use either your card or to be open the door by the security team.
The presence in Berlin of one of my favorite companies is quite modest compared with the strong branding I am used with in other part of the world, but it seems that they are smart enough to understand how to address the local market. In other words, you know that you are big but the measure of your greatness is the way in which you can contribute to the local economy. For instance, the Google specialists offer a lot of support for startups looking to develop their advertising plans - via Google, of course.
