Apart from being a beach bar/restaurant where you'll actually eat well, at night a lot of nice people come here and it makes a great atmosphere with good music and of course, some spectacular sunsets. For people who don't like environments with a lot of people, it's advisable not to go in August. It's better to go in June or July.
The Pirate is a snack bar located on the beach of Es Arenals, in Formentera. You can get there via a road, on the road to Sa Mola Savina, which at the entrance, has a sign with the number of kilometer 11. It is a small piece of wood, and from a distance you can see the pirate flag flying. It has four wooden tables outside, but at sunset it gets very full and you will see people literally sitting on the sand and rocks, waiting for the sunset. Here you can enjoy a beer, or perhaps a mojito, which taste great, and you can relax watching the sun go down. When it is about to fall, the waiter, as if imbued with the sun, puts on the song "For you Volare" by Andrea Bocelli, and the song when it starts is the last leg of the sunset, and just when you leave to see the sun, the song ends, all perfectly coordinated. Everyone applauds, and wait for the next day, when they can return.
