It is easy to meet them. Gaira, BE, Docle, Rhapsodia, Van Gogh, Bar Nena, Home (Santana), These girls are in one of these places or the other every Thursday, Friday, Saturday - depending on who has the best promotions. Don't be confused - this is not for the feint-hearted or for those looking to pay cien. They can be had but because of the cost of the club etc. it is a pricey concept. Some of these girls can be found at venues such as Hotel M on occasion and have even seen a few at the Rey (but rarely). These girls feed on the wealthy ex-pats and ticos in Escazu and Santa Ana as a rule. My $.02
A great way to check out the action is to invite a favorita from the sportsman or Rey with you to party - you will both have a great time and you will get an idea of what the next level up looks like!
Peace, love, and happiness for all.
