It’s important to understand the difference between club and nightclub in Costa Rica.
Many a visitor will ask for the best night club only to be pointed in the direction of a strip club. In Costa Rica a nightclub or “night” is always a strip club, a “club” is everything else, ie. a disco, a bar where there is music and dancing, even a swingers club.
Important to always be specific in what you are looking for. Always ask!
