After working together on numerous projects, the owner of Fitz’s Root Beer again reached out to Spiegelglass Construction to build Fitz’s SoCo, the new South County location of the storied brand. The 9,000-square-foot restaurant, which seats more than 200 people inside with additional seating on the patio, includes a working vintage bottling line viewable from the main dining room, an old-fashioned dairy bar and a private room for large parties.
