Solidly average for breakfast at ~20 a person. We ate here one morning because we needed something quick. They have a self pay kiosk were you can charge the meal to your room and I've never seen a line for those machines.
Some dishes were better than expected, like the pinto beans and my personal favorite, the fresh-made crepes with macerated strawberries powdered sugar and whip cream. I'd eat nothing but those and coffee if we go back.
Some other items were sub-par to be sure. The scrambled eggs for example were obviously powdered and reconstituted, poorly. The orange juice was very acidic, like hurt my mouth acidic.
There were lots of middle of the road options to meet all appetites. The country fried steak with biscuits and gravy for example were well cooked, not tough and dry. The breakfast burritos were more like chimichangas, rolled at both ends and fried. They're small and crunchy with an acceptable flavor.
Basically, act like you should at any buffet: look with your eyes and judge how the food looks before impulse reaching for the spoon and you'll do fine.
If it were a bit cheaper this would rate a four star. There's just too many other good choices in Vegas at or below this price to give them more than three stars. If you've got an hour, walk over to Eggslut at the Cosmopolitan for a bacon egg and cheese sandwich instead.
