Spella Cart Closed 'Til February 15

Because it's never too late to be servicey, a quick report--with bonus image from a gold starred tipster--that Spella, the 10th and Alder espresso cart that just opened a stand-alone stand-up caffe [sic] down on 5th and Alder, is closed until February 15th. Which is just in time for it to operate as the best possible post Best/Worst Day Ever-hangover (physical, emotional, pick your poison) cure. The intrigue here is that they're closed for "necessary training." As opposed to either "unnecessary training" and/or have all the baristas gone horribly off-pull?
