Come for the view. Drinks are extremely expensive ($18-20) I've been here when it has been a lounge or club. I prefer the lounge as it is a bit more relaxed. I also like it when they open the windows so you can hear and feel the fountains. I like the lounge also because they change the music playing to whatever the fountain music is. Very different from the club atmosphere where it's whatever DJ is spinning.
