Dimitiras Chestnut, 9, tries his first oyster at Columbia's premier food fest, Viva la Vista, Saturday. Chestnut liked the bivalve and was ready for more. "He eats anything!" explained his mother. Some eighteen local bands performed on three different stages and over twenty restaurants were on site to keep everyone entertained and well fed at the annual family event.
