The earliest records of this coffeehouse's existence state that it opened sometime in the early 19th century. In the 20th century, the place hummed with the presence of painters, writers, and artists of every persuasion. Today, like most of Venice
, the artists are gone, but the coffee and cocktails continue. Caffè Rosso has a rollicking aperitif hour. The bar itself is small but cozy, with an old coffee press machine and a scattering of tables and chairs outside on Campo Santa Margherita in Dorsoduro.
