Visited on May 20 and charged with credit card.
The contactless transaction was not finalized immediately, it took 2 days for the 50CHF reservation to be reimbursed and final amount billed.
Here I got more power than in Friedhofwägli, which reinforces the belief that the other charger was limiting and not the car. The 44kW start power, 40kW continuous here might have been the car limiting.
Like in Friedhofwägli, the start screen also said max 80A, but that cannot be true either given the actual power delivered during my test session.
There is construction work at this end of Grundackerstrasse, you can only drive in the western direction. So if you are coming from the west you need to drive all the way to the town hall to come back from the other side.
I first tried plugging in when parking forward, but the cable isn't long enough, even with my tiny car... It's a good thing if there are spaces available in the row opposite, otherwise turning around is a bit complicated. I think it's a better idea to enter the wrong way into the parking if you need to park backwards, since the charger is the last parking space before the exit.
