We're planning on it for our Spectro/Wishes night at MK, also. Never eaten there, but have always wanted to try it.
It does get a bad rap, but I've noticed that a lot of folks don't feel the spag. and meatball is worth $18. They have some other choices - per their menu - so we plan on trying some different things other than the spag.
We love the Lady and the Tramp movie, so that plays a part in our decision.
