Based on my first trip, Beijing Express is very good. Mongolian beef and General Tso's chicken and dumplings were all better than the same offerings by other Chinese in the area. They gave me a lunch special price on a Sunday at 3:03pm, which was very appreciated. The portion sizes are substantial, the vegetables in the Mongolian beef were fresh and plentiful. The location is clean, and they deliver which is awesome. It's nothing ground breaking, but it is now my go-to Chinese place. Keep up the good work!
