Pirata Bar is one of the attractions of Fortaleza itself. It is only open on a Monday. All of the music is live, such as the stylish Forró, Axé and other great artists. It's cheaper to book your tickets via your hotel. July Trindade proclaimed that it is the busiest place in the world on a Monday and not without reason.
The club is very busy on Tuesday, with live Forro music. It's open on Fridays as well but there's less atmosphere. You have an entry ticket and they write down your drinks that you pay for when you leave (necessary to be able to leave).
