I am not a fan for any reason other than the atmosphere; the view is freakin' amazing and the window in the floor that lets you look down 18 stories or whatever it is is freeeaaaky!!!
Drinks are very expensive here, so I suggest you take the route that I do when I go here: forego the vodka redbull and just get an absolut on the rocks, a little dirty with extra olives--this will save you about $10/drink.
Anyway, check it out if you're trying to impress a lady or guy and want to be able to speak with them without yelling over crazy loud music.
