A very close friend of mine owns this bar. It looks tiny from the outside, but it has two rooms you have to pass until you get to last one which is a discofloor. I play music there from time to time and I am always surrounded by nice people und friends.
This place is like being in the Canary Islands, where my hometown is. The wonderful botanical garden has around 22.000 different plant species. I can find here all the tropical species from the island where i grew up: birds of Paradise, palms or dragon trees.
One of the most beautiful pieces of Berlin actually is a piece of another city (Al-Hillah, Iraq). Normally Berliners are laid back and like to hang around, drink beer and chat till sunrise. Sometimes they do get excited though, and then they start taking old war-battered stones and piecing them together to (re)form walls. The results are great as can be seen all over Berlin, but the Ishtar gate in the Pergamon museum is where they’ve really outdone themselves.
This museum of photography is really great, and the highlight for me after the inspiring exhibitions is the good coffee and great cakes at their coffee place.
I find myself there almost every second week for a drink and a slice of cake. The food is perfect, the ambiance is nice and it's really alive as a lot of people are coming directly from the running exhibition. At the entrance you can find an interesting bookstore and the best photoautomat of the city right outside.
Last but not least, it's only some meters from the Helmut Newton Fondation ( which doesn't have a nice coffee place itself yet ).
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).
