I have eaten at this buffet for breakfast four or five times. The pancakes were dry, the vegetables looked anything but fresh, and much of the food just didn't look good. For a few dollars more, you can hike over to the Mandalay Bay buffet and get a WONDERFUL (by comparison) breakfast.
The high points of the Roundtable Breakfast Buffet were the Omelets and the Mexican bar (good meat here). Everything else was inedible to my picky eyes.
