Tryst just never gets old.  I love the ambiance, music, people, and have never had anything short of a great time.  The first time I went there with a group, my husband got WASTED. At 3:00am, he stumbled out of the bathroom and walked straight into the bouncer.  Needless to say, he was escorted out, but even then they were VERY professional and never rude.  We all totally understood and left laughing.  We've been back to Tryst every time we visited Vegas since then.  Great place that lets you have fun without being a-holes after you've drank too much - hey, Vegas isn't the same when you're sober!
