What don't they know? Venice is a small, insulated city made more intimate by its completely pedestrian layout. The locals know where to eat. They know the alley shortcuts that save you 15 minutes on your commute. They will tell you to abide by the high water alarms or risk getting caught by rising waters. If you're looking for the best gin and tonic in town, they will direct you to the lobby bar at Hotel Londra Palace or suggest, only for the view, to consider lunch on the roof terrace of Hotel Danieli.
