I have been to Italy many times and I assure you, you will not find better Gnocchi than Villa Gallace's gnocchi.
They absolutely melt in your mouth (and I am drooling just typing about it). My wife and I try gnocchi at every Italian restaurant that offers it, but Villa Gallace wins the gold hands down.
Chef Marcello is an amazing chef and we have never had a bad meal at this restaurant. The wine menu is fantastic, the service is first class all the way, and Luigi is an impeccable host.
You would absolutely be doing yourself a disservice by not enjoying a meal at this restaurant while in the area. Everyone that I have talked to that has enjoyed a meal at Villa Gallace's all agree that it is one of the best, if not the best, italian meals that they have ever had... Even in Italy.
