CHP may tell you to move either way...and it'll probably happen at an inconvenient time like 3am.
They're not any official RV parks people do Park out by the beach but I can't say I would recommended pretty isolated
They have a campground nearby...about 2 miles
A lot of Yelp/Google profiles are not run or frequently checked by the restaurants in question. I would call or go in person to ask.
I recommend you contact the restaurant, I would not stay there without permission.
