One show that you must spend the money to see is Love by Cirque du Soleil at The Mirage. A spectacular show with great music, fantastic stunts and gorgeous visuals that represent the evolution of The Beatles and their music while woven into a story of love, loss and life.
Be sure to head to the Revolution Lounge before or after the show for a signature cocktail.
If you want to escape the blackjack tables, there are a number of great shows to see in Las Vegas. As a Beatles fan, Cirque du Soleil continues to put on an excellent musical/acrobatic tribute to the band.
The Mirage has several good restaurant options for a pre-show meal and there were $15 minimum tables right outside the entrance to the theater.
