This upscale Peruvian spot is offering its pisco sours for $5 all day long on Saturday. (They're normally $11.) Can't make it this weekend? They also offer the deal every first Sunday of the month; we could get behind a few lazy afternoon pisco sours combined with the killer views of the Bay.

Since Cantina's bar team doubles as the importers of Campo de Encanto pisco, they take their pisco cocktails very seriously. From 4-9 p.m. on Saturday, they'll sell you a Pisco Sour for $5, and Guitar Box Story will play live music from 7-9.

As befits a place that has "pisco" right in the name, Pisco will have $5 pisco sours all evening on Saturday, from 5 p.m.-1 a.m.

A pisco sour at this Latin tapas spot will run you $3 from 4-6 p.m., and $5 for the rest of the night. They'll have free bar snacks like fava beans and chulpi (otherwise known as corn nuts).
