La Barrica (sp?) is a dominican disco in POP. They play merengue and bachata mainly, it is very very dark and very very loud. Great place to go though, you will see some fabulous dancing.
I wouldn't bother with Crazy Moon - it is a disco in one of the hotels at Playa Dorada (Paradise Hotel, I think), they play a mix of music, but all the sankis go there to pick up the young girls whose moms won't them go outside the resort gates

They think they'll be safe in Crazy Moon . . .
