Visited on April 12 without charging.
There are no gates, the parking uses a parking meter. The parking meter has prices for round the hour and Sunday, but as far as I know the parking closes with the store. I was not able to visit another day when I drove by on Sunday as the gate was closed at the entrance.
The charger is down the first row, you have no choice but to drive in front of it when following the loop.
The parking spaces are angled, it might not be ideal if your charge port is in the rear.
