Restaurants in Varenna, Bellagio, Menaggio

Silvio in Bellagio. Local food typical of the region.

If you can take ferry to Tremezzo, La Fagurida is terrific, with a great view. Also local fare. No pasta!!! (Restaurants favoring local food will not be serving pasta in this region!!).

I've written about both of those here; the report is old but those restaurants are still going strong; make sure to book ahead, wherever you choose to dine:
