"As a personal note, this restaurant at one time in Las Vegas was the ultimate gathering spot for the Whose Who in Las Vegas. On any night in 70's and early 80's you could get a great meal and see some of the most famous and infamous people of Las Vegas and the world. It will be a pleasure to spend time in this famous restaurant again, long live the tradition of The House of Lords! Sahara Hotel and Casino"
