Dave Hoekstra gets a taste of “the aloha spirit” and Fong Fest, a festival of Polynesian-flavored music, dancing and shopping at Chef Shangri-La, 7930 W. 26th St. in North Riverside. Owner Betty Fong Hlavka and tiki anthropologist Dave Vasta are in-studio to discuss the restaurant’s rich history and tiki culture in Chicago as a whole. We also get some surf tunes courtesy of Lorenzo Friday and 13 Tikis, who are appearing at the fest.
