I spent a couple of months working in Ravenna, in the north, in the late 90s. While there, we often ate at a place built like a huge barn (so it appeared on the outside), made of stone and wood. Everyone ate at long lines of tables, all together. My favorite pasta dish was fettuccine pasta with a thick white, creamy, parmesian-cheesey sauce that tasted a whole lot like Alfredo sauce...
We called the restaurant "the Volume House", but that wasn't it's real name. Been so long I no longer remember it. But they had the best food there!
Also, on the subject of Marco Polo - many (maybe not most, but a significant number perhaps) scholars are thinking that the stories of Marco Polo are invented, that Marco Polo was a merchant who never really left the Mediterranean region, but rather related to a writer, later in his life, stories that he'd heard (plus some he flat-out invented).. There are too many things that simply don't match up with real life, including his descriptions of monsters and fairies and all other manner of crap and no mention at all of common things like foot-binding. Of course, some of what he had to say was verifiable (such as the use of paper script for currency in place of precious metal coins, for example), but could have been learned by talking to other traders.
As is the story that he brought back pasta to Italy perhaps a bit exaggerated. In fact, his "account" mentions that he had a pasta in China similar to lasagna, which means he was already familiar with pasta before he went to China. Many peoples over the millennia used pastas. Perhaps, if Marco Polo really did travel to China, he brought back a different recipe...but it's more likely that pasta was brought to Italy during the Arab conquests of Siciliy in the 5th century.
