John Currence’s catering kitchen is the place to eat right now in Oxford, Mississippi. With the chef’s fine dining restaurant, City Grocery, closed for renovations, he’s experimenting with high-minded street food and hosting four weeks of "Big Bad Pop-Ups." Week one featured Atlanta’s Eli Kirshtein, of Top Chef fame, who made Israeli favorites like falafel, latkes, and crispy cauliflower; coming weeks will bring guest chefs Kelly English, of Restaurant Iris in Memphis, and Andrew Ticer and Michael Hudman, who run Memphis’ Andrew Michael Kitchen and Hog & Hominy.
