If you want fs then you might like Seamans Club or Le Petit Chateau, could also try El Capitan, Club Carolina and Casa Blanca
A word of advice - if you see a lady you would like to be with - make sure to have a drink and chat a bit before you go back to the room - almost guaranteed bad service if you don't.
Le Petit Chateau is at the Salt Pond. If you take the back road from the Salt Pond toward the Zoo you pass both Crystal and Caroline's and Seamans' Club is at the main road (on the left) where the back road ends in intersection. If you keep going straight toward Oyster Bay you will see 3 casas on your right up the hill, Casa Blanca (The Border Bar) being last after Defiance and another smaller place. There are a couple more in P'burg proper but not worth the time. It'll take 3 hours and 4 or 5 Carib's (Le Petit Chateau had $2 Red Stripes on my last trip) to meet about 250 Chicas from all over the Caribbean and Latin America. Casa Blanca and Crystals are all Dominicanas and most haven't worked the casas back home. They are carefully screened.
The Strp Clubs (esp. Platinum) are fun too and a great place to work up a lather before going to the casas.
