My boy D and I hit up Foundation Room after a long day of work and sightseeing. We were just looking for a relaxed vibe and a drink or two.
Luckily I had a connection to get us on the list, so can't really comment on cover costs. The bouncer at the bottom of the elevators was cool to us and we got in pretty quickly.
FR was actually smaller than I thought it was going to be, but then again I think there may have been some other (private?) rooms that just weren't open the night we went. The VIP couch areas take up a good amount of floor space in the main bar area (especially if people are dancing in the free space). But the view is great from the balcony and the drinks aren't too expensive.
For the most part I enjoyed the crowd. A couple of groups in the VIP couch areas who seemed to be having fun and were an attractive crowd. A handful of cougars on the prowl, and your complement of single guys and gals with their eyes constantly scanning the crowd.
The decor is very Zen with a large Buddha guarding the entrance to the club once you step out of the elevators and some great wall decorations. The combination of serene decorations and mellow music made for an enjoyable couple of hours.
I'd recommend people to check it out. It's not wild and crazy like some other Vegas clubs, but that's part of the reason why I liked it. More low key, mellow, loungey, than your typical over-the-top Vegas style club. Most people probably wouldn't want to spend their entire night here, but it is definitely good for a couple of hours.
