Time Out says
At the luxury Gritti Palace Hotel, Bar Longhi is a classy setting for cocktails, either in the historic interior salon or on the canalside terrace.
Enjoy views of the Grand Canal and La Salute from the terrace of this elegant hotel bar, or sit inside it main salon, which glitters with mirrors, crystal and Murano glass, and is wrapped in antique wall-covering and 18th century paintings. With cocktails priced for €19 and the cheapest bar food €22 (for a ham and cheese sandwich), this is not a place you wander into after a day of sightseeing, but rather an event in itself. A smart casual dress code applies.
Time Out tip: If pricey cocktails aren’t your cup of tea (sorry), Bar Longhi serves traditional afternoon tea, with finger food, every day from 3 to 6 PM.
