Berlin in May with friend

[Ihatenicknames]

My friend and I are off to Berlin for three days in May. Any recommendations for bars, restaurants and sites?
Thanks

Visit the East Side Gallery (largest bit of the wall still there).
Memorial to the Murdered Jews in Europe and Brandenburg Gate.
Main museum worth a visit.
DDR and Stasi museum if you have interests in history.

Recommend a fat tyres bike tour, they take you to all the main sites and give great explanations. It takes several hours but you’re constantly getting on and off the bike to look at things/hear about the history so the cycling isn’t intense.

Yes yes yes to fat bike tours!

The Rooftop bar and Grace Garden at Hotel Zoo are incredible. The Rooftop is only open in the summer, so not sure whether it will be open in May.
NENI is expensive but completely worth it for the view alone! We found it rather difficult to find, so if you make a reservation (you should, it’s popular!) ask for directions. You can have a drink first (or a coffee afterwards) in the beautiful Monkeybar on the same floor. We found the lunches quite affordable.

To visit the Reichstag building you will need to book online now. Museum Island is great. I think there is a restaurant at the top of the TV tower.
