Let me qualify what follows with this statement. We generally like Disney restaurants, do almost all of our dining on site, and have tried quite a few of the Disney offerings.
We just ate at Tutto on Friday, and won't be hurrying back. The seating, at least along the walls, was tight, and while I don't mind chatting with nearby diners, I prefer it not be obligatory. Also, I really don't need the servers posterior in my face when the people at the next table are being served.
While the appetizer we chose (Antipasto Misto) was good, our meals left us unimpressed. My wife had the Bucattini Pasta, which was okay, but unremarkable and I had the Tagliatelle Egg Pasta which neither of us really liked.
The atmosphere is little (if at all) changed from the Alfredo's days, which is not a bad thing.
While Tutto is not necessarily considered a signature dining restaurant, it is certainly priced so (our appetizer, which is for two, ran $24, and our entree's were $24 and $19, and this was at lunch. The same meal at dinner would have been $26/$26 and $25 respectively.
Lastly, we found the restaurant, which was not full at the time, to be very noisy.
Good luck and I hope this was some help.
