This week work hard so you can play harder at all the Free events. The Tonga Room turns 70 so what better time to visit one of Anthony Bourdain's favorite spots. Get down with the animals at the SF Zoo for Fur Ball on Friday night. On Saturday, test out the perfect costume before Halloween at the SuperHero Street Fair. On Sunday, expose your leather and latex or look on as others do at the annual Folsom Street Fair.
