This dish, which takes quite some time to prepare, is the showpiece of Cavaliere Gian Paolo Belloni, Chef and Proprietor of the Zeffirino Restaurant in Genova. I never knew so many ingredients could work together so well to create such a superior pasta dish. Sinfonia del Mare, although presented rather theatrically, was a very pleasant surprise! You can omit a couple of the fish varieties if you have trouble obtaining them.
