As a local, I am offering some insights on what might be most interesting, delicious or exciting on a trip to Germany.
Arriving in Berlin, you will be overwhelmed by the sheer size of the city and what's on offer. Although a classic, I do recommend eating “Currywurst”. One of the best places to do so is Curry36 in Kreuzberg. For a great view while sipping some cocktails during the evening, head to Andel's hotel's bar Loft14 in Prenzlauer Berg. You will have a great view towards Fersehturm from this spot that not many people actually know about (not even Berliners).
While in Dresden, I recommend heading a little away from the center towards the 3 castles on a hill beside the Elbe's riverbank. Lingernerschloss is the place to be to enjoy a coffee or drink while taking in the stunning view of the city and river. Schloss Abrechtsberg has a beautiful garden to wander along with your loved one while Schloss Eckberg which reminds more of a castle is now home to a luxurious hotel to treat yourself with.
After visiting the famous Church of our lady in the center along with plenty of other people, head to Kunsthofpassage in Dresden Neustadt. When the rain starts to fall, this colorful drain and gutter system turns into a charming musical instrument. Also, the other facades in this backyard are designed by sculptors and artists. Small shops invite you to shop a bit around after exploring the alleys, restaurants and bars in the surrounding area.
Arriving in Leipzig, getting “above things” is what you may want to do first. Take the elevator at Uniriese, pass the turnstile and find yourself overlooking the city from the tallest building in the center. All the old buildings in the center will be “at hand” now. Walking through the city, I recommend a stroll through Mädlerpassage, a former trade fair building that reminds you in style of Milano. It also features the famous restaurant Auerbach's Keller where Goethe was inspired to write Faust.
For some impressive art in a former factory building, head to Kunstkraftwerk, an art Exhibition place and event venue located in what used to be the Big Leipzig Tram grounds. The power plant was initially built around 1900 to provide energy for the new tram network of the western part of the city. Energy was produced using coal at that time. The space is nowadays showing digital art and two massive immersive art shows where 360 projectors fill the entire hall with video installations allowing the visitor to be right in the middle of the experience.
Fancy German bread? Then head to Bäckerei Lotzmann. Real “Sauerteig” will make you get a taste of German bread tradition.
For German beer and some traditional snacks in the evening, Beyerhaus is the place to be.
The cities of Berlin, Dresden, and Leipzig are well connected by trains. No matter in which city you are, you will reach the next one in 1–2 hours by rail.
Celebrate Christmas Midnight Mass with Pope Francis at ST. Peter's Basilica after enjoying a semi-private 2 - 3 hour tour (max 10 people) of the Vatican Museums including the Raphael Rooms and The Sistine Chapel ending with a privileged entrance to St.Peter's Basilica.
