Dennis is going to Berlin for a couple of days, with a friend. When he went to Avignon, I asked for calissons. If he was going to Paris, I would ask for macarons, if he was going to London, I would ask him to bring me back some salt and vinegar crisps, and some cheese from Neil's Yard. If he was going to Brussels I'd ask for chocolate, and so the list goes on.. but what should he bring me from Berlin? Help?
