If you're deliberately looking for it — you will definitely find/experience it at some point.

In my personal experience, Berlin is very foreigner-friendly.

I'm told both things, actually, in equal measure. That there's ample casual racism compared to London and yet it's incredibly foreigner friendly. I'm married to a German so I have spent a lot of time in Germany, just not Berlin yet. No idea why my question was downvoted, I was quite interested to hear what the poster had to say about the scene.

Berlin can be quite different from the rest of Germany. I haven't seen any sign of racism here at all, especially in the start-up scene.
