Though you can find ones in Long Beach, Pasadena and the Valley, the L.A. Greek Festival is the largest of its kind in L.A., hosted by Tom Hanks and Rita Wilson, who’s of Greek descent, and attracting more than 15,000 visitors annually for the last 20 years. You can listen to traditional music, watch dancers and gorge on typical Greek food, whether it’s savory souvlaki, flaky spanakopitas or syrupy baklava. Better yet, take dance lessons for added authenticity.This year’s theme is “Mediterranean Cuisine, Health, Taste and Beauty”. You can also hear Latin DJ music, a nod to the neighborhood’s Byzantine-Latino quarter, and go on one of the hourly tours of Saint Sophia Cathedral, a gorgeously ornate Greek-Orthodox church, built in 1952, that’s a designated historic cultural landmark. Saint Sophia Cathedral, 1324 S. Normandie Ave., Pico-Union; Fri., Oct. 4, 5-11 p.m., Sat., Oct. 5, noon-11 p.m., Sun., Oct. 6, noon-10 p.m.; $5. (323) 737-2424, lagreekfest.com.
