Hard to predict if this will go on even after pandemic times, but people of all ages and social groups have very obviously taken over public spaces here in Munich by hanging around, or rather staying around. You bring your own drinks and glasses or cater yourself from the restaurants/cafes/pubs in the neighbourhood. The quality level of the drinks is high (craft beer, selected wine) and people bring real glasses, not plastic. Drinking culture so to say, which, I guess, will stay for a while for good reasons. You are not glued to a seat or table and it’s an update with no further costs: a self-catered bottle of wine for 25€ plays in a different league than a restaurant served bottle for the same price.
Wiener Platz is one of those new locations frequented mostly by locals. The place gets very nicely crowded, more densely or more distantly depending on the ever-changing rules and restrictions. The feeling is a bit like being on the cobblestone version of a garden party.
