How Florian's early patrons looked one can see in a brilliant little picture by Guardi in the National Gallery, No.2099.The cafe boasts that its doors are never shut, day or night; and I have no doubt that this is true, but I have never tested it in the small hours.
Oddly enough there are no restaurants in the Piazza, but many about its borders on the north and west.

The visitor to Venice, as a rule, eats in his hotel; and I think he is wise.

But wishing to be in Venice rather more thoroughly than that, I once lived in rooms for a month and ate in all the restaurants in turn.

Having had this experience I expect to be believed when I say that the restaurants of Venice are not good.

The food is monotonous, and the waiting, even at what is called the best, the Bauer-Gruenwald, say, or the Pilsen, is leisurely.
