In the end, what makes you feel at home in a city is a place like Altes Europa, offering a daily changing menu of simple food and a good selection of wine. This bar/café/restaurant is a Mitte institution. Where bars tend to be rather touristy or over-the-top stylish, Altes Europa keeps it simple and sweet. This is the kind of bar that could easily become your second living room.
The service is rather rude and you should be able to cope with the Berlin humor—you might have to anticipate total ignorance regarding what you ordered and the completely different dish or drink your server shows up with, shrugging his shoulders. But if you can sustain this taunting by shooting a joke back, then you’re sure to have found a fun place to keep spending time.
