a bit of a clue for you if you choose pacha on fri is to book a table in the restaurant. Sounds a bit crazy but trust me, its awesome. There's no entrance fee ( a saving of anything up to 55euro) plus the food is excellent, the drinks are about half price of the same ones in the club and there's no waiting in that massive queue. We do it every year now and one year our plane was delayed, we arrivede 2 hours late, bought a shed load of champagne and beer, ordered a starter each ( about 10 euro) and as long as we'd spent at least 40-45 euro they said get yourselves in!!!
Cant get any better in my opinion!...as for the night, I've been 8 times in last 5 years and had very mixed evenings. One was so busy that it completely ruined the evening, others have been awesome so i think its a bit of suck it and see. if they have a good night then so do you!!
