I went through the same thing with our last trip to the World. I read and read and read review upon review of all of the World Showcase restaurants to find the PERFECT restaurant for my DH and I to enjoy our wedding night dinner. We finally decided to throw all caution to the wind and try Alfredo's. It was wonderful!! They had the BEST caesar salad...yum! I remember having the caesar salad, the fettucine alfredo, 2 bellini's, and the dessert sampler platter. DH and I had the exact same thing and we both enjoyed our dinner immensely.
I realize that there are lots and lots of negative reviews out there, but I've learned to forget the reviews and try it myself to form my own opinion. I'm sure there's something out there that I find horrific that someone else finds wonderful!
