Since you have a car and can venture out of the block...
On the way to and in Cabarete:
Sea Horse Ranch. Spectacular ocean side setting and very good food in a high end gated community.
Coconuts Hideaway Beach, Playa Encuantro. Again, beautiful ocean front spot, good pizza
Front Loop. On the beach, good service, good breakfast and lunch, very busy on weekends.
Mojitos. Busy all the time. Salads and... Well guess.
Nectar. Vegan options, ocean view very nice food.
Vagamundo. As good a coffeehouse experience as you will get anywhere.
On the way to and in Puerto Plata:
la Catalina, a little out of the way but nice views, big place crazy busy on Sundays with locals and live music. Funky car collection and parrots .
Las Palmas, great italian, beautiful old house, fantastic gardens.
Patio Frida, by the pink instagram street, very good Mexican, very cool setting.
Visited all these spots within the last few months.
