When Jeff Solari stepped inside 266 Main St. in downtown Old Town last November, he told the building’s owner he thought it would have to be torn down. Almost a year later, Solari is opening up a second location of his Brewer restaurant Kosta’s in the building, he said. He expects the restaurant to open in mid to late November. The opening will mark a homecoming for Kosta’s, which was located in the same spot before Yamas Bar and Grill opened there in 2010.
