i can confirm this. kiss is like garbi (it reminded me of some village-discotheques here in germany.
there was also this irish-pub in playa d´en bossa. ok, it´s tiny and cosy. but i ask myself why the hell people go to ibiza and then viisit the IRISH PUB??? i mean, there are irish pubs everywhere, and i think once you´re in ibiza there are other "new" nightlife-experiences you can go for.
same with kiss.
