The shop downstairs is worth a visit if you are nearby, if only to ogle to large chocolate models of Titanic, Brandenburg Tor and Reichstag. But to really enjoy this location, head upstairs and treat yourself to a hot chocolate drink and maybe a chocolate cake or dessert. Has to be the best ht chocolate I have ever had! Service was polite and swift, prices in line with central Berlin - neither seemed to have suffered from this being a tourist attraction. Well worth a short visit to warm up on a cold day.
