 Recent studies have mitigated some of those assumptions, but still show three-year failure rates of all restaurants to be about 61.4%, and that franchise restaurants fare slightly better than independently owned locations.During the early morning hours of February 13, 2008, a Taco del Mar franchise in Vancouver, British Columbia was destroyed by a large explosion which damaged several nearby businesses.Police confirmed that the blast was caused by an arsonist who had placed an accelerant inside the restaurant, then set it on fire.
