Here in Higuey I go to one of the "upscale" peluqueria called "Bacan York". I pay $150 pesos for a haircut and shave, with tip it's 200 pesos. I receive great attention got friends with the barber (Monchy) and I can make phone appointments, etc. get a ring to "come now" to avoid wait, etc.
They have TV, cable, A/C, freezer w/beers, and use quality shave/after shave creams etc. They do machine cuts but on request (my) barber would use scissors.
Other barber shops may charge 100 pesos for the same thing, but it's the "experience" one pays for. You always are part of the great conversations going on, hear the latest "chismes", fun stories, etc. This is also a gathering place for many people so the place is never boring.
