Spindler is my favorite brunch stop when I'm in the mood for fresh eggs and classy but-yet-simple athmosphere. 

Wim Wenders shot Wings of Desire here. It's a quiet place to work and definitely a gorgeous place to visit. Combine it with a visit to the Philharmonic, just across the street. Affiliation is 30 euros per year and you have lots of desks all over the library to choose from.

One of my favorite sophisticated-but-casual places in Berlin. Everything is delicious and the restaurant is cozy and minimal at the same time. It is the right place to have a wonderful dinner with somebody special without being too anxious about the dress code :)

Best record store in Berlin. A great selection of Rock, Folk, Indie, Wave, Industrial and especially the huge floor dedicated to House and Techno Records. Staff are typical Berlin-Style - not very friendly but very knowledgeable.

ABC is Berlin´s Eggs Benedict Mecca. This laid-back, fun little shop will provide you with one of the city´s best Aussie brunches - provided you reserve or are willing to wait for some time. But the eggs, the coffee and the Bloody Mary really make it worth.
