We have lived close to DC for six years, and in the general area for more than 20 years, yet somehow managed to miss this hidden gem. We've eaten in perhaps a dozen chinese restaurants, but now this is the place to go for great chinese food in the DC area. My ethnic-chinese wife ordered a lamb dish that was the best lamb she has ever had. We had spring rolls for appetizers, and they were light and flaky with no excess oil. I've eaten "spring rolls" more times than I remember, but never anywhere as good as these.
We visited in late afternoon when there were few other customers, so I cannot judge service or quality when they are busy. One thing I can confirm is that their prices are no higher than other chinese restaurants, and the portions left a lot to take home. Great value!
Downside: In Bethesda, where parking has essentially disappeared. This restaurant is just a couple blocks from he Bethesda Metro station. And, I'm sure you can always order takeout and have a passenger run in while you idle outside.
