Headed to the Mission for cocktails on Saturday night?  Then you better make a pit stop at Rare Device, which will be hosting Argentinian illustrator and painter Irana Douer's first-ever U.S. solo show, Hidden Treasures.  Douer creates very vibrant and colorful portraits of women that look angelic at first, but after a closer look the ladies seem to be hiding something.  The artist "is interested in how relationships, particular situations, or even ordinary things can affect a woman's life.  Hidden Treasures... explore(s) what's hidden, different and mysterious."  Saturday from 7 to 9p.m.
