Berliners are odd people - they do have a Currywurst museum though. Right by Checkpoint Charlie, of course.
How could you turn this down:
Since basically everything in the museum is interactively designed, you can touch, test and participate: virtual Currywurst making, a spice chamber with sniffing stations, a sausage sofa to relax, audio stations in ketchup-bottle shape with iconic songs about the Currywurst or an original snack bar on wheels.
