This place is one of a kind and someplace I plan to revisit often...If you are staying at Mandalay Bay, Excalibur or New York New York, you can easily walk to and from Burger Bar.
The menu has the most exotic burgers you could ever thing of. Burger Bar has a Kobe Beef Burger that cost something like $60. I just stuck to one of the $10 burgers in my price range and was still very impressed.
This is one of the spots you need to remember next time you are deciding where to go.
