Our hotel was right across the street from Boca Marina so every morning I couldn't resist going for breakfast and dominican coffee and we always had a pina colada, or coco loco if I ever got out of the water! I found Neptuno's to be the most expensive, with the most beautiful decoration but generally had a formality that didn't suit me.
Boca Marina was ok, with a cool atmosphere and fine for food. I found boca marina and Pelicano more to my taste, the first for the evening and the second for the morning because it was the most relaxed of all, the waiters move in caribbean rhythm and time, the music was Dominican and it is the only one that fits to the place.
Boca Marina is the last in the line and had more waves when it was windy, especially on its eastern side. The Neptuno's and Pelicano's were nearby and they form a closed bay with calm water , so even when it was windy it was perfect.
We spent our mornings here, rather than on the main beach. Although it is a beautiful beach, alive with color and music, sometimes it gets annoying with the vendors and people who don't understand "thanks but NO".
