I charged here on Saturday! Was a little low on charge and was at IKEA picking up some new cabinets. While partner was checking out items and doing order pickup, I moved the car from general parking over to here. Everything works! It was pretty busy though— almost all stalls taken on the first weekend of opening!
If you buy anything from IKEA, you can easily load the car while it charges, by the way. It's right next to the entrance/exit.
I think it would be awkward to come here if you weren't going to IKEA already. You have to get in line to enter the parking garage and deal with slow-moving traffic that is finding parking spots. It's not like this Supercharger is right by the entrance. And to leave you have to go through the whole garage including through an area where everyone is pushing carts to/from their cars.
