There is a restaurant by the port -- from where the ferry leaves -- that serves delicious minutas (small fried fish), fresh cherry juice, and other Dominican delicacies.
About 20 minutes from Sabana de la Mar is the Ca?o Hondo hotel, that those who visit this area should at least stop by to have lunch. If you can, overnight there also, it is lovely -- bring sweaters cause can be chilly. Delicious Dominican food. Definitely worth a stopover. This is the place to stay when taking the Haitises excursion.
