About this business

This little diner on Oceanside Pier combines the essence of the 1950s with an atmosphere of pure "Southern California". Patrons walk down a wooden bridge to get to this diner, a singular building located at the end of the pier. In the tradition of a 1950s diner, burgers and fries top the menu. Try the Ruby Dooby Double Cheeseburger. Remember to try the fountain treats! Oreo shakes, root beer floats and vanilla cokes are just a few of the options.

Very slow service. Not that busy. Beer was not cold, salad was not cold & refreshing as it should be. Very disappointing after a long walk done the pier.

Excellent place to get a root beer shake ! If you’re on the pier in Oceanside stop on by , it’s before the very end of the pier , where the ocean starts
