Shouldn't take too long - its kind of in the middle of the island between Santa Eulalia and Ibiza Town (kind of). Nice setting.
However well worth the time to go....we had a great meal there last year with a big group of us....the ambience is lovely as its set in a real pagoda style building and its what you would expect from a top Ibizan restaurant.
Bar is very nice as well and when you walk in there are people dressed up as Budhas amongst the really tall bamboo that you walk through.
You will love it - overall its very well done.
(they did a live set of chilled music when we were eating too which was v cool)
