What is meant by "Riccione style"?

Riccione is an Italian town located on the coast of the Adriatic Sea, and part of the Emilia-Romagna region of the country. That's the area which gives us Parma ham, Parmesan cheese, and other foods you typically think of as Italian. Along the coast, fresh seafood is easily available and extensively eaten. Not being able to view the recipe in question, I can't tell you much more than that. The seafood dishes I ate in that area were usually grilled, and delicious. The "alla Riccione" probably refers to this, and the recipe was likely inspired by fish dishes prepared at the various restaurants and in homes in that town. You just have to keep in mind that although we lump all Italian dishes into one big category, they are in fact somewhat specialized by region and influenced by the varied geography and locally available produce.
