Dear Richard,

I’m on my way to Düsseldorf for some very dull business, but I’d much rather be in Berlin for some very un-dull culture. If I route through Berlin, I’ll be able to spend a day there. I’m happy to cram as much into 24 hours as possible, and as I just watched that sexy German TV series Babylon Berlin, I’m eager for culture, sure, but also—can I be frank?—a little decadence. What might you suggest?
