Being on a plane for five hours without internet meant that the moment I disembarked in D.C. on Tuesday, I had about three hours of emails and Gordian knots to untie. I purposefully picked a hotel in McPherson Square so I’d have restaurants within walking distance. (I went to Washington to organize an event celebrating NASA’s Voyager spacecraft, which are exploring an exotic region at the edge of our solar system.) Of course, by the time I actually disconnected myself from the internet in my hotel room, it was 8 p.m. So I headed to Chinatown, betting that area would have a restaurant that was still serving food. I was happy that Chop’t was open — I wanted some fresh vegetables after eating dried snacks on the plane. The Tuscan farro salad — with mozzarella, artichokes, roasted tomatoes and a ramp vinaigrette — was the best salad I’ve eaten in ages and the perfect antidote to a long day.
