Not as outstanding as XS but I would say that Tryst is still a beautiful club and is up to par, absolutely!
Guestlist is still available on Saturday nights which is great since many clubs in sin city don't offer guest list these days on weekends (as in, absolutely no cover for both women/men). Otherwise, I believe it's $30/male or $20/female cover.
The inside is elegant and still holds that "glam" factor that Vegas is known for. Crowd is good and the music offers a variety of tunes.
