If you're looking for cities that feel more "German," then you should check out Cologne and Nuremberg. For whatever reason, Cologne was very empty and the weather was pretty gloomy. This actually made for climbing the 533 steps to the cathedral's south tower a bit more bearable.
The museum was actually pretty extensive with 3 floors dedicated to the history of chocolate, how it's manufactured, economics of chocolate, a greenhouse, etc. There is also a floor where you can actually see the machines at work and this chocolate fountain. The lady in this picture, who is now your best friend, will give you a free chocolate dipped wafer. Enjoy some free chocolate along with the great view!
Nuremberg is worth a visit not just to see Hitler's favorite Germanic city. Yes, you can visit the Nazi Rally Grounds and Documentation Center, but the city itself was very lively and charming with its old world charm.
