From Hannah, the organizer:
We will meet in the Michaeligarten beer garden in Ostpark on Wednesday
28th June at 18.00. If it is raining, we will postpone and meet on
Friday 30th instead. If the weather looks bad, we will discuss on the
“Munich?” thread on the forums whether or not to postpone, so check in
there for a decision.The nearest U-Bahn station is Michaelibad on the U5. You can bring
your own food into the beer garden or buy food there, although you
won’t be able to bring in drinks.I will bring a teddy bear to put on the table so people can find us.
If you need to get in touch, you can post in the “Munich?” thread on
the forums or email me on hannah.in.munich@gmail.com.Thanks so much!
Have a good time!

Update from Hannah: there are storms forecast for this evening so we will meet on Friday instead. Possibly somewhere indoors. Will update with new details asap.
Further update from Hannah: we are meeting at PotAsia Ost at 8pm tonight. It is in Berg an Laim, Baumkirchnerstr. 21. More details and map here: https://www.potasia.de. As I might be a bit late, forum member Mercy will be at the table with a stuffed froggy, but feel free to still use my contact details if you need to get in touch.
Directions from a local:
from Tram 19, Haltestelle Baumkirchnerstr. From the corner of Kreillerstr. and Baumkirchnerstr., walk past the Aumüller bakery and it’s about halfway down the block, across the street from the Maibaum.
From U2 Josephsburg, take the exit for Kreillerstr, turn left, and walk a long block to Baumkirchnerstr. From there the directions are the same.
