I have to say that I've had meals at Olive Garden that were far superior than some I've had onboard a ship. Actually I've had some good food there. I'm not expecting "authentic Italian" but I've walked out saying "That was good.". I've also walked out saying: "I'm not going back there again".
There is no way you can do pasta in mass quantities and not have it turn to mush. I never order pasta unless it's in an alternative restaurant. My wife loves pasta but every time she orders pasta in the MDR it is usually a mushy blob. At least, most of the time, Olive Garden has edible pasta.
