I had the Creamy Chicken Alfredo the other night.... basically it tasted a lot like the standard Pizza Hut alfredo sauce that you'd get with the fettuccine, but with pepper added to it and baked with a bit of cheese on top. The pepperyness was a good addition I thought, and being able to add a 1/2 order of breadsticks for $1 was nice. I spent another $1 and added cheese to the breadsticks - yum! You can't specify this on the internet ordering though.
It's basically made from a lot of stuff PH had on the shelf already, but combined in a novel way and repackaged, so if you're hardcore Italian it might disappoint.
Not a bad value for 3-4 people and overall, I enjoyed it even though I thought it was a bit short on chicken. Might have to try the Meaty Marinara next time.
