San Clemente is drawing on the success of a restaurant to revitalize its downtown. .... When Dave Donaldson floated the idea of opening a restaurant in San Clemente's downtown, many tried to dissuade him... But Donaldson didn't listed and now city leaders and downtown merchants credit him for helping trigger the transformation of the quaint seaside village into an upbeat attraction. .... "BeachFire started it all," said Councilwoman Stephanie Dorey. ".. Now you can't find any place to park."  Michael Kaupp, a planning commissioner and member of the Downtown Visioning Task Force, said their goal is to build on the vibrancy of  Del Mar, the town's main street and where BeachFire is.
