We had friends who visited Venice every year for so many years and they would stay for several weeks. They had some celebrity status, as he was a well known author. In southern California we were neighbors and always dined at their favorite restaurant, which was The Grill on the Alley in Beverly Hills. They were all about eating meat.

I have never dined there, as I love seafood. Small trivia note is that IIRC, George Clooney had his bachelor party there.
