I am a geocacher from Norway visiting Berlin for a couple of days, to visit the christmas markets and get the cozy christmas spirit. This Sunday is the first Sunday of Advent, so this will be a great time to meet up. I have googled a Café that looks nice, that is Café Dazwischen. It is close to the U-bahn and open until 10PM :) Possibility to bye some food or coffee, have a look at the menu: Cafe Dazwischen.
I have not made reservations for this event, but it does not look to busi on Sunday evenings (I just want to mention it).
I`m looking forward to meet both local cachers and cachers from other countries :) Feel free to bring any tb´s that wants to travel to Norway, or other places.
Hope to see you there!
