Funny you should ask, because we just returned from the Star Princess Saturday, and I indeed had one of the worst entrees ever ... and the winner(?) is ...
*****The frogs legs******
Now I have had these before fried, and they indeed taste like chicken. But when it was presented to me on Princess, it was a white opaque, covered with some crushed tomatoes, and appeared as if the WHOLE frog were laid out on the plate! Frankly, it looked like a frog that had been run over by a car and was bleeding profusely.
Honestly, it was enough to make anyone with Norwalk virus run screaming for the bathroom.
