Events in Costa Rica can be found online here and here.
Plus the atmosphere of the bar and clubs are more sophisticated, lending to more formal attire than flip flops and bathing suits.
To fit in with the locals in any town, you will want to dress a lot sharper with a nice top or dress, nice jeans or skirt, and shoes or high heels.
Costa Ricans dress in their cowboy best and go to these festivals with their families where they enjoy a tope (horse parade) during the day, and toros (Costa Rica’s bull-friendly version of bull fighting), delicious food, games, rides, and a variety of lively Latino music and dancing during the night. When I first moved to Costa Rica, I would ask about the good nightclubs in town and get a good hearty laugh from the locals.
It’s important to understand the difference between club and nightclub in Costa Rica. It’s easy for Costa Ricans to assume a girl is mixing up the lingo as there are no male strip clubs in Costa Rica, and a girl seeking to go to a nightclub usually only goes with her boyfriend, so there is no need to ask around.
The majority of Costa Ricans live with their parents or extended family until they are married.
It is not acceptable for them to bring a date home to spend the night, no matter how old they are or whether they are a woman or a man.
One of the jokes that gets the most laughs here in Costa Rica says that the highest cause of traffic accidents is due to men taking their eyes off the road to look at the pretty women walking down the street – this will cause a pileup!
Despite all the ogling, male chivalry is alive and well in Costa Rica (unless you are on the bus).
Most people go out on Fridays and Saturdays, but there are exceptions when the club or bar hosts a discount night, or especially popular, a ladies night. For example, Monday nights in San Jose, Cuartel de la Boca del Monte is a hot spot.
Ladies nights are always guaranteed to be popular because ladies get in for free and are treated to free drinks.
The Costa Rican woman will be absolutely clear about what she wants from a man.
