You can find good techno in almost any large city because those DJs tour a lot. I don't think you're going to find something like Berghain in any other city, but if your city has any kind of underground scene at all, there's going to be good techno nights. Like I could go out tonight and see Loco Dice and Marco Carola in my city in the US.

And don't assume that people in other cities don't get it. There's lots of underground clubs where people that go out are 100% into it for the music and "get it" and aren't just going for bottle service and VIP or whatever.
