Best Italian food ever? Nope. I don't think Italian is really Wolfgang's bag. But, it is absolutely better than Olive Garden, Johnny Carino's, Buca De Bepo, or any other chain restaurant I've been to.
The service is slow, even when the restaurant is empty. I like to think it's because they are making everything from scratch. But whatever the reason, allow yourself some time.
The atmosphere is about as authentic as it can be considering its location. The prices are about what you would expect for a nice restaurant in a more expensive casino. The portions are plentiful, so take advantage of that mini-fridge in the room.
