DAYTONA BEACH — As national retail and restaurant chains flock to this city's fast-growing LPGA area, Vittorio and Catarina Tiano quietly opened their new eatery on West International Speedway Boulevard in January. "If this location (at One Daytona) didn't pop up as being available, we probably wouldn't have opened a second location," said Catarina Tiano. She and her husband also run a Tiano's restaurant that opened in 2009 next to New Smyrna Beach Municipal Golf Course. The new Tiano's across from Daytona International Speedway is one of a handful of new stores and restaurants that have opened along ISB in recent months.
