Stop by Hideaway Bar on Pedro Clisante after 10pm on Wed or Sat nights. There is a group of Haitian guys that run a Latin dance night those nights and they run a dance school. They are very nice, excellent dancers, and you can see them in action and ask about lessons. Lessons are 500 pesos per hour, I think plus u can go there 2 nights a week to practice. They teach bachata, merengue, salsa, tango, and some other dances. Saturday nights have been kinda slow, Wed nights better. Makes for a nice night out - different from the usual scene in Sosua.
