For our weekend meeting, let's go to the Castle Pub.
This place is very good, and it is just a couple of minutes away on foot by S-U-bahn Gesundbrunnen (U8, S1, S2, S25, regional train), so very easy to reach from the whole Berlin.
German beers, as well as beers imported from UK, can be found here, so everyone should be able to find something to drink. Food is also available.
The aim of this meeting is to get to know each other, so everyone is welcome, either you are New in town in Berlin, or you have been living here for ages.
So we are looking forward to seeing you, for chatting and drinking together.
