C/O Berlin: Exhibition (most of the time photography).
Sammlung Boros: A nazi bunker repurposed into a fruit storage place in the DDR then into a club after the fall of the wall then finally into modern art gallery. It's only guided tours where you learn about the art pieces and the history of the building.
Stasi Museum: Museum about the DDR's state security service. The building used to be the headquarters of the Stasi.
Dokumentationszentrum Berliner Mauer: A free museum about Berlin's wall and in my opinion the best one, you can see a complete section of the wall with a watchtower as well as archive videos.
In Berlin like everywhere in Germany there's a big choice of delicious beers, don't be shocked to see someone opening a beer in the s-bhan after leaving their workplace. To my knowledge, Berlin has two main kinds:
Pilsner: Despite what everyone born in Berlin will say to you this kind of beer is bland, it's great for quenching your thirst but that's about it. The two main brands are Berliner Pilsner and Berliner Kindle. They taste the same yet everyone born in Berlin prefers one or the other (often depending in which part of Berlin they are from).
Berliner weisse: This one is a bit more interesting, it's a very old and sour beer. When you usually order it in a bar you will get it served with a sirup but it isn't so good. Recently sour beers are trendy again, which means that microbreweries produce great Berliner Weisse that you can enjoy without the sirup the ones from Brlo and Berliner Berg are great examples.
There's also Radlers which is a Pilsner mixed with citrus fruit soda, it's refreshing and low in alcohol so perfect for hot days.
You can of course also enjoy beers from other parts of Germany, the most common being:
Weizenbier/Hefeweizen: Wheat beer served in high glasses, personally I like Franziskaner the best.
Helles: Light lager, my recommendation if you don't know what to drink. Augustiner is my go-to beer.
Gose: Another old and sour beer that has its origin in Goslar.
Biererei: Great place for fancy beers but fuck it's expensive, they also have a bar in the same street, also very expensive.
Bars & Breweries
BRLO Brewhouse: Berliner microbrewery, their biergarten is the perfect sunny evenings hangout place.
Hofbräu Berlin: A big and ugly building opened by a Brewery from Munich, it's touristy but still interesting for the atmosphere, especially in the evening when it's full and people are dancing in front of the live folkloric band.
