With an estimated group of 14 and no reservations for brunch on Father's Day, I pressed my luck and went to Verandah first to see if they could accommodate us. Behold my Vegas luck, someone with a group of 14 canceled and we would have a nice semi-private room for our group. Only downside would be that it would be inside. If you have a semi-small group or don't mind waiting, I'd recommend trying to get seated outside on a nice day. It's right next to the Four Seasons pool and seems very relaxing.
Some people in our group ordered a la crate and some got the brunch buffet. Two most impressive contraptions of the meal: the Donut Robot and the fresh peanut butter maker. The donut robot makes donuts by itself and the only need for a human being is to dip the donuts into toppings (but I'd recommend just trying a plain donut fresh). They had an omelette station that had both crab and lobster meat. Traditional breakfast buffet fare including frittatas, bread pudding, lots of fruits and pastries, etc... They also had fresh squeezed juices.
I guess the only negative was the cost. +$40 for the brunch buffet after tax/tip. Being in the Four Seasons hotel, I guess this is to be expected. However, still a reason for a dock of a star. I haven't really eaten at the other casino buffets for breakfast/brunch, so I can't really compare. But I'm fairly certain they're less expensive and might even offer more fare.
