I frequent the Mandarin hotel as the lobby makes for an ideal place for quick business meetings.  Following one of those meetings we invited our clients to the private dinning room within Twist.  The food was amazing as were the parings suggested by the staff. (The foie grass was melt in your mouth delicious) The only draw back is the size of the room, only fits 16 and is a very snug fit at that number. This is counter balanced by the great view of the Las Vegas strip, all in all a great experience.
