This was the choice for my final breakfast in Las Vegas during a recent stay. I live in Chicago where the original is located but they don't serve breakfast there.
I got a mushroom and cheese omelet served with fried potatoes and toast. Boy, everything on the plate was great. The omelet was just right, not overcooked and oozing with melted brie. The toast was thick slices of hearty bread. And the potatoes were a nice accompaniment.
Bottom line: Its convenient, right on the strip so you don't have to walk through a gargantuan hotel and casino to get to it. The service and ambiance are really nice. For breakfast, it's not as expensive as you would expect. Oh, and the food, it's great.
The experience of the dinner menu translates to breakfast. A solid five stars for breakfast.
