Came here with some friends before going to a concert. Burger Bar is located on the bridge/walkway that connects Mandalay Bay to the Luxor. They are pretty pricey for the food but it's on the Strip so that's to be expected.
We sat at the bar and had a wonderful server. I wish I asked for his name! He was attentive and gave opinions on what his favorite food items were on the menu.
I got the baguette burger (cooked medium) which came with melted truffle Brie cheese, tomatoes, onions, lettuce, and pickles. The words "truffle" and "Brie" is what made me order this dish. I was a little worried the baguette would be too hard but to my surprise, it wasn't at all! My burger was cooked perfectly. The meat itself didn't have a whole lot of flavor, however, the truffle Brie cheese made up for that. This came with skinny fries (my favorite) because their fries are more crunchy which is what I prefer.
If I had an event that's either at Luxor or MB, I would eat here again. It's a great restaurant to just chill, relax, and eat.
