It is an experience.
If you don't don't mind wading through crowds of tourists to eat.... Italian food, it is worth trying once. They have quite a variety of things there, little shops and little restaurants to check out. It is worth walking through.
However, if you don't want to dive in to busloads of map holding tourists, don't wish to put up with the lines and noise, for just average food - at high prices - I'd recommend going to a different spot.
It is an experience - but not a great place for a meal.
