Kw is a great art institute situated at the backyard of a very eastern part of town, place for many other small galleries. Auguststrasse is worth the walk and Kw is worth the stop.
Haus der Materialisierung is an association of various local initiatives and institutions that research, practice, and work on the topics of sustainable management and climate-friendly use of resources.
...and it works!
If you want something a little different from your beer, try Lager Lager.
"We are an independent bottle shop and taproom in Neukölln with a passion for all things beer. Choose from our 8 rotating taps and 250+ bottles, with new stock arriving each week. Drink in or takeaway a Growler bottle of your favourite beer using our counter-pressure bottle filler, which guarantees freshness."
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 :)
