In the middle there is some kind of kiosk, but closed and for sale. It's a rest area. The area along the highway=service around the property is designated as a public parking lot (fee=no), capacity=50, if densely parking.
Former name of this place seems to be Jussy Boules. Photo taken from the North East corner.
