I have written before and I will continue to write that IMHO the Verandah at the Four Seasons is THE BEST place for breakfast in Las Vegas. Period. Service, setting, food (Huevos Rancheros!) are all top notch.
And just a quick note. Many people on CH ask about Breakfast Buffets in Las Vegas. The Four Seasons serves a brunch on Saturday's and Sundays that will rival many on the strip. Not the biggest selection but the quality is unsurpassed and for what others charge, the $35 that the Four Seasons charges is beyond fair.
