Visited on September 7 and did a short charge with credit card.
At the time GOFAST had still not announced the location on social media, but they did it on September 10 https://x.com/gofast_swiss/status/1965750912959627613 The location is still not listed on their website though.
The charger is behind McDonald's. You drive around the building anti-clockwise.
It's a bit annoying that the chargers are at the end of the row, if you need to reverse into the last spot when the parking is full, you'll need to do a 180° then reverse to the end of the row. But for all the times the parking is not full, it should be easy with the space available.
I assume more lighting is planned, because it's not very good at the moment.
The chargers are A400, but I don't know what the maximum power actually is. My battery was quite full, I was only taking 22kW. In their announcement, GOFAST said 300kW. The screens say 400kW in very large font.
Contactless was 65ct/kWh, with a 50CHF reservation. The reservation appeared under the name "Fabrikstrasse 1", and the final transaction under the name "Fabrikstrasse 0". Not a very user-friendly name, even more confusing considering the charger address in the Greenflux backend is on Badenerstrasse.
The toilets in McDonald's don't require any code.
Neither the McDonald's nor GOFAST station were visible on Google Maps at the time, but they are now.
