Located on the top of Mandalay Bay, Foundation Room has an awesome view. It's kind of like the Mix Club that's located on top of The Hotel, but has a Buddha theme going on.
I went here for my cousins after party and thought it was cool, it wasn't crowded. But around 11:30, there were a lot of people. I only noticed two rooms which were not that big. The main room and the room that is located near the hallway.
