I loved stepping out of the airport doors into the mugginess Tuesday night. It was a reminder I was back on the East Coast. It’s been about two years since I’ve been back to downtown D.C. and I’ve definitely noticed some changes. Chinatown, for example, has cleaned up a lot and now is home to foodie salad joints like Chop’t. (I totally recommend that place, by the way. I had an amazing steak salad with chimmichuri dressing. They also had a machine with a variety of Boyland sodas on tap.) Even though it was a sultry night, the sidewalk was thick with people. I even passed some teenagers hanging out on a corner, listening to iPods tucked into portable speakers rather than the boom boxes of old. I’m glad that the hotel where I was going to stay — the Residence Inn in the midst of enormous cement bureaucracies — was overbooked and they tranferred me (free!) to the Renaissance instead. There’s a lot more going on in this area, which they call “Penn Quarter.” But what’s with the name? What’s wrong with calling it Chinatown?
