While Tempelhof is of course known for it's great music and dancing, it is also a very friendly social community. Visitors and residents often spend time simply chatting about life, the universe and everything. (Also discussing where to get clothes and how much SL is lagging at the moment)
The too most popular meeting points in Templehof are outside of the theatre itself (The landing point) and in the Kommandantur (Headquarters) which is located next to the Theatre (as shown above).
Visitors are encouraged to come and chat with the local residents.
While visiting Tempelhof, why not take a look around.... the scenery (click here for examples) is beautiful and there are lots of secret places to be found, there are some darker elements to Tempelhof, but that may be what you are looking for.
