Seattle went years with nary a Potbelly, the holy-hell-popular sandwich chain. Now the Chicago-based biz is marching in fast and furious.

Or at least fast. On December 6 Potbelly plans to open its third area outpost in six months. The newest branch is at 1111 Third Avenue, not far from the first shop here, at Fourth and Pike. (The other one is in downtown Bellevue.)

The company has hinted at ambitious plans for the Seattle area, but a Potbelly rep says further locations still are not nailed down.
