Going strong since 1958, Castiglioni's wonderful deli has evolved to include an enoteca (wine bar; situated 50m around the corner) and a lunch-only restaurant. Sample dozens of local vintages with plates of sweet prosciutto, or take lunch on the pleasant outdoor patio. The menu, which includes all manner of charcuterie plates, lake fish and mountain meat dishes, is surprisingly refined and superb value.
There are copious vegetarian options too.
