Hi Danyelle,
I was in POP / Sosua last week.
SOSUA:
D'Classicos is the only disco open these days (D'Latino of the same owner was closed, certainly on weekdays). Since High Caribe is under remodelation, all gringos and off course the prostitutes with them gather in D'Classicos. There are always a number of male dominicans hanging out as well, it's not really clear whether their the pimps or just trendy guys. I agree that it's a good disco with mixed music and a good sound system but it is not a place to go if you are looking for dominican atmosphere.
Go to Sosua Car Wash or Plaza Caribe on weekends; Plaza Caribe is an outdoor bar/disco behind the former Copacabana disco just before getting to Sosua Sol. A nice bar in Batey is Cowgirl with only dominicans.
A bit further away between Sosua Abajo and La Union on your left side is El Salman, a typical dominican place.
PUERTO PLATA:
I went to La Barrica disco which was loud and dark as usual with lots of merengue, some bachata and some very old romantic boleros. The disco on the Malecon is closed. You should also try La Canita so they told me.
PLAYA DORADA:
There is a new disco opposite the Playa Dorada complex on the highway. I don't know what it is called but dominican friends recommended it to me.
MONTELLANO:
There are now weekly bachata/merengue concerts at Las Brisas de Camu disco in the Montellano village. Very dominican and safe place. Another good bar there is Entre Amigos near the sugarcane factory, music is loud though.
Enjoy it!
