Just at the moment when most everyone is trying (at least to some degree) to eat healthier, it's Restaurant Week in Columbia. The event runs from today through 1/17, so it's actually ten days.
Maybe that's a metric week.
In any event, looking at all the participating restaurants, I'd have to recommend Motor Supply. You get three courses for $40, and their food is always great. Drinks at the bar are on point, as well.
