You may recall a year or so ago I posted an entry about the new Park Block that was being planned at SW Park and Taylor in downtown Portland.  Included in the plan was a small, glass-enclosed restaurant space that had a lessee in place – and they planned to call the restaurant “Viola”.  Being a violist, that caught my eye, and even joked that violists might get a discount at happy hour or something like that.  Well, just days before the owner (owner of the now-defunct Roux, Dwayne Beliakoff) were to take over the space, there was an explosion and fire, and the plans had to be put on hold.  Today, happily, I discovered that there was a contingency plan: a mobile food truck that serves a scaled-down version of the eventual full menu to be available at the bricks-and-mortar location.  I had a great burger and fries, made fresh to order from only the finest local purveyors.  You might check it out next time you’re downtown, they’ll mostly be open at the lunch hour to start, eventually staying open later as different events take place around the park block.
