It’s House Spirits Distillery’s last Recession Proof Mixology of 2009, and they’re going out in style tonight at Sassy’s on SE Morrison. Oh, quit wrinkling your brow quizzically and pretending you’ve never heard of it.  As the invite instructs, “bring your good nature, open-mindedness, and plenty of $1 bills.” From 5-8pm, bartenders will be pouring $5 specialty cocktails like the The Dark Buck with Medoyeff vodka and pureed ginger, and The Bee’s Kiss, with Aviation Gin and housemade clover honey syrup. Bid RPM adieu until 2010, drink fabulous $5 cocktails, and see some boobies too.
