Visited Berlin for the first time in March, I loved it and would love to go back! Congrats on the move!
A few things i could definitely recommend:
Rhinoçéros Bar, which is up in the P-Berg area, was the single coolest bar I have ever been too.
It’s a hi-fi jazz listening bar, with absolutely amazing cocktails and charcuterie plates, friendly and awesome bartenders (say hi to Maxime for me!), super cozy and small with just a few tables and a 4-top bar. Highly recommended!
Also, there is no shortage of good food, however Umami Berlin had some of the best Pho I have ever tasted, and it’s a cute little traditional Vietnamese place with good prices.
