Spaghetti Carbonara owns everything. Try the gnochi dishes too.
If it's a real Italian restaurant, they won't have fettucini alfredo because it's not an Italian dish. Not to say it doesn't taste good, because it does. But if they put cream on pasta, for them there always must be something to go along with it, such as speck, mushrooms, seafood, or other vegetables. They think it's disgusting to eat just cream with noodles...I think it's rather tasty, in any case.
