The lack of a sign is no accident. The bar was inspired by addresses that operated out of sight during American Prohibition. The mystery used to be taken so seriously that customers had to give a password to get in. Now it is easier: you only need a reservation and, who knows, you might meet someone there who is your type. Maybe someone who also likes a certain sense of exclusivity, drinks classics like margaritas, daiquiris and espresso martinis, or prefers more creative mixes. On a menu of drinks named after films, Cantando na Chuva mixes vodka, dry vermouth, green-grape liqueur, lemon and sparkling wine.
