The Sala Atril is one of the newest and trendiest places to go out to attracting in the main a young affluent and carefree Cuban crowd who likes the general ambience that includes a mixture of techno and reggaeton in a large indoor up-market venue, which is not really geared to tourists. Do bear in mind that this crowd generally follows the party so when the party is someone else you may find yourself with the place to yourself. The entrance to the bar is just to the right of the main entrance to the Karl Marx Theatre and re-opened only in 2005. Generally the acts will begin to play at 11.30pm. The no-smoking rule inside means that there is a pleasant breathability to the air and that you generally find a large crowd squeezed together on the outside balcony.
