Chef Marcus Samuelsson (Red Rooster Harlem, Ginny’s Supper Club, Marcus at the Hamilton Princess & Beach Club in Bermuda, Norda Bar & Grill in Gothenburg, Sweden, and more) will be focusing on Washington’s Ethiopian cuisine in his Aug. 14 episode of “No Passport Required,” now on PBS. Outside of Ethiopia, Washington, D.C. has the largest population of Ethiopians in the world. The Ethiopian-born and Swedish-raised Samuelsson was also a guest chef at the White House. He filmed part of the episode in June at Das Ethiopian restaurant at 1201 28th St. NW — shown at right with Das’s Elizabeth Wossen and Sileshi Alifom. Photo by Bill Starrels.
