Coffee here was good, the Eggs Benedict was actually pretty good, and my wife had a corned beef sandwich on rye, and the service was pretty good - not too pushy, not inattentive.
Moral of the story for us, after visiting is: the better hotels have a better breakfast spot.
Nothing spectacular, but if I were to stay in the Luxor, I would definitely hit this place up and not really bother to venture out when I could get something pretty good for a reasonable price in a pinch.
