We've been twice and enjoyed it both times. I like the space and the theme - it's supposed to look like a old airport terminal that's been converted to a restaurant. It is a little less noisy than the average Disney restaurant, because of the big open room and carpeted floor. But it's not quiet like Citricos, say, or Tiffins.
Our service was good both times; a little slow for Disney, but frankly most Disney restaurants try to hurry you along so we were fine with that.
The food is good; it's run by the Patina Group, which also runs the Edison, Morimoto Asia, Enzo's Hideaway, Vivoli Gelato, and all the restaurants in the Italy pavilion at Epcot. It's not exactly adventurous, but it's well executed. If you're from a big city with great Italian restaurants, don't expect it to blow you away, but it's a significant cut above Olive Garden.
