Several nights a week this club, set in a grand former theatre, stages concerts ranging through soul, country, salsa, rock, jazz and pop. You can hang back in the relative obscurity of the bars or plunge down into the pit and boogie away before the grand stage. It’s like being at a rock concert of old. From about 2am, the place turns into a club that attracts a well-dressed crowd with varying musical tastes, depending on the night. It gets a little sweaty in the dedicated club room Sala B, which opens on Friday and Saturday nights only.
