Time Out says
Legendary Madrid nightclub Costello is the spot where you always end up hanging around for drinks after watching your favourite band. They always bring in quality acts, and it's not uncommon to come across musicians among the audience as well. Stay tuned to their Facebook and Twitter pages so you don't miss a thing. It can get wall-to-wall at weekends, but overall it's quite the comfortable venue. Bonus: they serve tasty cocktails.
