Imagine you have a guest from the USA. What places of interest would you like to take her him and why?

Good Morning, my American Friend

Are you excited about visiting me in Berlin, Germany? I hope so as we are about to visit one of the best attractions that can be found in here. Although, don't assume that we will only see the tourist places. I plan on taking you to the unfound underground spots so you can see a true side of Berlin.

Best Regards
