The research and energy to synthesise such a great volume of information to a palatable experience means this a must go in Berlin! Ask Bnaicker about Berlin Story Museum
You can do both on a combined ticket or just choose one or the other. We did both and spent around 3 hours wandering the bunker listening to the audio guide. (Included in ticket price). If you don’t know the history of Berlin then worth spending the time.
The video at the end summarized everything much better than the whole Museum. It is too packed with information and lacking in some details or overall picture that one just cant imagine/place the history. That being said, the video at the end was good.
