Just until recently this place used to be one big old Aphoteke (Pharmacy). They have kept the Apotheke's  dark wood Art Deco charm to use in benefit of great coffee and fantastic brunch (try the french toast and you'll see I'm not lying). 

Cosmoveda is a hidden xberg gem. It's an Ayurvedic supermaket that happens to come with a kitchen with it. There you can find a delicious Ayurvedic lunch menu (with soup, main and a little dessert) in 3 different sizes, prices starting at just 5,90. Not to mention you can shop the ingredients that you just ate in case you want to try to cook Ayurvedic yourself.  

The is an old geisterbahnhof, or railway station, in the Prenzlauer Berg district of Berlin, Germany. It is served by the Berlin S-Bahn and the M13 line of the Berlin Straßenbahn. The station opened on October 1, 1935, at the junction of the Nordbahn line from Berlin to Stralsund with the railway line to Szczecin where the eponymous street named after Bornholm Island crossed the tracks. As Bornholmer Straße station lay right at the Berlin Wall it was closed on August 13, 1961, turning it into one of Berlin's ghost stations, passed by eastern and western S-Bahn trains without stopping. After German reunification Bornholmer Straße was reopened on December 22, 1990. Today, you can still go there to see remnants of the wall, and where people flooded in when the wall came down in 1989. (In the evening of November 9, 1989, thousands of East Berliners and GDR citizens assembled at the bridge demanding entry to West Berlin. At 9.20 p.m. local guards were the first to open the checkpoint and allow people passing through freely to West Berlin, where they were greeted enthusiastically. The event marked the commencement of the fall of the Berlin Wall.).

A very nice little second-hand bookstore, including a shelve with international books in French, English, and Spanish too. Always nice people to meet and a great selection of art and cook books, for affordable prices.

A good place to drown your Berliner winter-melancholy. The bartenders are top notch and the interior is warm but stylish, with the inevitable retro vibe. Open from 6 till late. There´s also a legendary (and kinda expensive) restaurant next door, which provides the bar with some excellent snacks. Works for dates and for friends, but if you´re planning for a bigger group it might be wise to reserve.
