Visited yesterday without charging.
The chargers are in the underground parking for Migros and Denner. There are no gates, and doesn't seem to be any payment method for parking.
The chargers are in one corner, the parking spots are painted blue but no EV sign or text saying it's reserved for charging.
It's not written anywhere but I assume the parking closes with the shops since the only access is through them.
Everything west of the Bernstrasse here is brand new, there's still a lot of construction work next door. On satellite images it's just a field.
