The General Store
85 Avenue Portola
El Granada, CA 94018
Located across Highway 1 from Pillar Park RV. There's a little path that cuts across the field. It's located behind the fire department. It's rather a unique place because it's a deli, and a hardware store. They also have pumpkin ice cream.
They also have a few RV supplies.
If you don't want to walk, the easiest way to drive there is to take a right onto Highway 1 as you exit Pillar Point RV Park. Go to the first stoplight and take a left. Take the very next left and go about one block. Take a right at the fire department. It's on your left.
There's a full fledged post office across the street from the General Store as well.
