Palace Station already announced that the opening of their new buffet will be July 20th. I was there today and saw these introductory prices posted at the entrance.
Breakfast $7
Lunch $9
Dinner and Sunday Brunch $13
These are for Gold card holders and above. Prices for Preferred card holders are a bit higher and no card holders a bit more than that.
The buffet looks a lot like the new Palms Buffet. The old buffet on the 2nd floor has already closed.
