I can only comment on my experience with Bottle Service but for me, that is important. When people go to a nightclub and order Bottle Service for only two people and pay upwards of $1,000+, the expectations are going to be high.
That said, this nightclub never disappoints in that regard. They are unique in that they have a two-person table area so you don't get surrounded by the 4-6 guys who are all splitting a bottle and trying to get trashed while scoring women who want free drinks. There is one table in particular that is directly at the edge of the dance area and also is outside by the waterfall. It's hard to get but it is worth it because you get the best of both worlds: the beat and vibe of the club and the cooling effect of being outside. The only other place that has that feel is Hyde at the Bellagio but the fountains there can drench you if it's windy when the window is open.
The last time we went, my fiance' and I were treated well by the servers and we also did what we usually do which is request a security guy be assigned near us to keep the bottle rats and club trash from putting their drinks on our table and hovering around. We usually tip the security guy $100 right away and then it's basically like having a bodyguard there all night. I remember one particular point during the night where one guy was just standing there and not moving plus bothering my fiance' while I was away from the table and the security guy grabbed him and basically picked him up and moved him away and said "don't come back here, ever." That was classic.
I would recommend going here if you are a couple and you want the full experience without some of the downsides of going to clubs and ordering bottle service.
