Terrible food and grumpy service.
The food selection was limited, considering it's a buffet. The knife provided could barely cut the dry roast beef, brisket and pork ribs. The cooked to order pasta Alfredo wasn't very tasty. They did have salad items including spinach and avocado which, without dressing, were the healthiest things I've eaten in Vegas. The rest was dodgy Chinese and Mexican but once a few of the drinks took hold it was ok. The dessert selection was better than the food, but unless you only want dessert I wouldn't bother.
We got the all you can drink package but the waiter who served the drinks was unattentive to the point of rudeness, literally turning away after seeing I signaled to him. He improved after a few polite responses but could offer little advice on what drinks were included except a guttural grunt of "red wine white wine mimosa beer".
The sparkling wine was drinkable though somewhat sweet, the red wine was truly awful. I think we got our money's worth but only through persistence.
