I wonder what the box-like thingy is just inside the restroom entrance. There's an oval plaque above it with an arrow pointing down.
(there's an identically shaped sign inside the snack shack)
My best guess is the box like thingy is the end of a standing only eating area. Customers took their food here rather than take it to the beach. There is likely a trash can out of view. My other guess is this area does not have restrooms. The restrooms are behind the snack bar.

"Two cups of Adohr milk
, please."
(or maybe the Adohr sign is for ice cream)
