Sa punta , la gaia , jondal and I like la Paloma a lot
Honourable mention amante just for the view not so much the food.
And chains ...cipriani ( for the laydees) and Zuma.
I've been there, but not stayed at the hotel. It's ok ... people are friendly but it's full of 40+ oldies !!
I guess it's nice to capture some of the essence of the original Ibiza without selfies and camera phones. But there's plenty of that available in the younger places still if you know...
