Just ok - nothing worth going back for. My wife liked her meal but mine was not so great. The noodles were all stuck together so it was a giant glob of dough and the shrimp were overlooked and very tough. I brought it to the waiters attention but he didn't make it right.
It was our anniversary and I thought this would be a good place to go for ambience but they put us right next to a large party so at times we could not even talk to each other. There was no one else in that part of the restaurant but we could hear a screaming baby in the other room. Definitely not the place for a quiet adult dinner.
We topped off the evening with a gondola ride but I don't think it will ever bring us back to the Alto.
