Sodo has a new sushi bar and grill. It’s called Sodo Sushi Bar and Grill. It took over the space of the oft troubled Olv, whose name had no hidden meaning or acronymic message. Sodo, or SoDo, is shorthand for south of downtown, which is where it is. And that’s a good place for this new restaurant, too, because there aren’t any other sushi joints anywhere nearby. Bars and grills, yes, but not sushi bars and grills. All that seems to have been required to transform the Olv space into a sushi restaurant was to plop a refrigerated case on top of the bar. Voila — or dekiagari, as they say in Japan — sushi bar.
