definately Cafe Mambo or Savannah, bot play chillout vibes till the sunset is over then the music switches to chilled house.
Cafe Mambo has Pete Gooding as their resident chillout dj, well worth listening to his sets. Then this normally follows by the warm up pre-parties by the big nights being held at Pacha. IE pete tong on fridays, roger sanchez, darren emerson etc. You get to watch and listen to the big dj's for free, well worth it. Saw Pete Tong last year on the beach out side Cafe Mambo, he played some wicked tunes and was in my element dancing on a beach at 2am.
Cafe Savannah doesn't get the big big big dj's but last year i saw Trevor Nelson dj here, oh yeah and saw Stonebridge do 'Put Em High' live at 1am for the hed kandi pre party, that was wicked!
Definately visit both of these bars, they r only about 50 metres apart and both have amazing views of the sunsets
