The 36 best things to do in D.C. this weekend and next week

You thought last weekend was busy? Saturday brings dozens more embassies to tour, as the European Union celebrates its culture with its annual Open House. A packed lineup of festivals includes the annual JxJ Film + Music Festival, a bonsai festival, the Arab American Cultural Festival, the Bethesda Fine Arts Festival and the 10th anniversary of Books in Bloom. The drive-in theater at Union Market returns, as does natural wine tasting on the National Mall. A plethora of anniversary parties includes H Street NE brewery Henceforth, which is turning one, and beloved Mount Pleasant theater Suns Cinema, which is marking a decade in business. It’s also Mother’s Day weekend, so we have ideas including flower arranging, walking tours, pet photo ops and the Mother of All Yard Sales.
