Pasta - best done at home in my opinion. But something like a Vongole is hard to beat from a good restaurant. My personal favourite is open seafood lasagne - but then, I make that at home and it is the dogs danglies

Risotto? I tend to avoid north of the Alps - but there is a cracking restaurant in Ticino which does one 1 dish - Risotto with Funghi and Gorgonzola - stunning
Polenta? Good at home - but can get some stunning stuff in the right restaurants. Although I am sucker for the down and dirty sliced stuff you get in work canteens
Pizza? However nice the ones my wife makes are - they aren't the same as a good restaurant pizza. But it has to be good. Thin, and made with a dough that has some flavour - arguably the best I ever had was in the EUROHOTEL in Monza.
