I have never eaten at the restaurant at the San Clemente Palace. When we are in Venice, we would make use of their free shuttle to enjoy the hotel grounds and get away from the crowds in Venice. The hotel itself is a refurnished monastery and it has a cold institutional feel. Big, imposing with high ceiling and long corridors, it lacks warm of any kind. Whenever we there in April/May or October, it is mostly deserted. I think it caters mostly to business and wealthy tour groups. Unlike the much closer to Venice Cipriani, which is always busy because it has views of Venice. The San Clemente is very remote with very little connection to Venice and I can't imagine any refurbishing can make it less so. If I am staying there, I might consider eating there.
