We just got back from staying at the Swan and eating at Il Mulino. It was very good, but not as good as the original in NYC. The original is my favorite restaurant and we go there about once a year (that's all I can afford as the prices at the original in NYC are crazy!). Anyway, if the name were different, I would probably go there again in a minute, but I had high expectations because I was comparing it to the original so I was a little let down.
Having said that, it wasn't much more that any nice Disney restaurant (and even some not so nice ones). The service was very good and the food was good. They gave my wife and I champagne for my birthday.
If you are in the mood for a good Italian meal in a nice setting, go for it!
