Here is a restaurant in Zaton that can be reached by car and boat (more fun). Its called Restaurant Gverovic-Orsan. There is another picture below of the view from a table.
This is a great little bay in Zaton. It is very difficult to reach on foot, but by boat it is easy. Crystal clear water and very sheltered. Ideal for snorkling, boat picnic or just sleeping, except for the noise of crickets!
