Stayed in Torno before and saw this place - this time, stayed in Como and went for dinner in Torno. Perfectly possible to take a boat from Como (or Cernobbio) to Torno and one (or a taxi, if it's too late) back.
The restaurant offers many meat and lake Como fish dishes and a large selection of wines. Our menu was OK but you really eat here for the amazing view and atmosphere on the terrace. If you're lucky (and we were) you'll even get a table just by the balustrade to the lake
