For the lounge....
Located in Mandalay Bay, my friend Dj Icy Ice was spinning the Pacquiao after party here so we scored free entrance and no wait in the line.
This place has more of an intimate setting, which is a great if you want to take a break from the crazy clubbing. Cool vibe, decent size interior, dim ambiance and the best part an awesome view of the strip from the 64th floor. Outside there is a small patio. Inside, there is a small dance floor, the bar and some seating. We were able to snag some seats but I think most of it is reserved for bottle service. The music was awesome, a few dj's rotated and mixed a lot of hip hop and old school beats.
Another cool thing about this place is it's both dressy and casual. Casual meaning maybe a pair of jeans and a cute top, not your juicy velour suit. Guys were wearing jeans, a t shirt with some cool kicks. Didn't see a bunch of drunk skanks falling all over the place or shady guys all up in our faces, so that was a plus.
So I recommend checking this place out if you're looking for an alternative to the club scene.
