I can just imagine Proust all bundled up on a warm day in Venice. How it must have thrilled him to be there. The first view of Venice, when traveling down the Grand Canal, does not disappoint.
Take a look. Proust on Travel
I wonder what he ate. My two favorite Venetian meals were the "Treasures of the Adriatic," a fantastic plate of seafood whose memory makes me want to drool, and the appetizer of ravioli with cheese sauce at Harry's Bar. The Bellinis were nothing special, but ye gods, that heavenly pasta and the incomparable cheese sauce against which all future sauces must be compared and found lacking.
The pizza, however, was molto mediocre. Dumb to order pizza in Venice, yes?
