1) The annual Ethnic Expo international festival? It’s what’s for dinner — and lunch, and late-night snacks — from 11 a.m. to 10 p.m. Friday and Saturday at Second and Washington streets outdoors in downtown Columbus. It’s the biggest local menu of the year, from bratwurst, thanks to the German hosts this year, to efo riro, a Nigerian vegetable stew. Besides the 30 food vendors, ample entertainment fills the schedule, plus a bazaar — and the most cosmopolitan mix of people this city has ever seen. Information and schedule: ethnicexpo.org.
2) I’ve known Columbus resident Laura Andrews as a top-flight violinist since the early 1990s. Many others also know her as a first-rate instructor of young students. See for yourself at 6 p.m. Wednesday when the free Andrews Strings Studio violin recital featuring 25 students ages 8 to 18 unfolds in the Red Room of the Bartholomew County Public Library, 536 Fifth St. in Columbus. Information: 812-379-1266 or mybcpl.org.
