Guarana is a great place to go after all the other bars have closed, Sunday is the best as they have live bands from four thirty.

Another place worth checking out in Santa Eulalia is Liquido Bar which opened this year in the port where the old Bistro Mariposa once was. It has great music, killer cocktails and probably has the best view across the marina. It's down at the Ibiza Yachting end of the Marina just past Sunseabar as you walk from Guarana.
