Berlin is more rigid, or compartmentalized than expected. With great German engineering comes great city design with insight into the mind of this culture. Pipes run along the length of streets similar to a power grid but I have not yet determined the use of these pipes. For history geeks, Berlin features many WWII and Cold War attractions including the Berlin Wall, museums, and memorials. The Berlin Wall is actually was taken down after WWII so separate segments exist throughout the city, mostly along the border of the Spree River. Do not be surprised if you do not find it initially. Just keep walking and you’ll eventually find it, with or without the help of a map. The food is average priced for a tourist location but the beers taste great (think American craft beer but better) with just the right amount of hoppiness and lingering sweet aftertaste. As the first city I have arrived in on this Eurotrip, Berlin allowed me to savor the non-GMO/frozen/shipped food here very much. Surprisingly the hostels are relatively inexpensive here with full breakfast. Even with the meat that Germany is known for, the portions are reasonable compared to America’s and most dishes come with fresh salad, a decent sized serving of vegetables. Unless you enjoy the WWII and Cold War history a great deal, I would not spend more than 2 days in this city. The other cities in Germany are smaller but also have specialties. For example, the BMW museum in Munich may be of interest to many. Note that even though Germany has the largest GDP in the EU, the buildings here are regular sized, unlike the corporate offices in the US which are huge.
