We were looking for a quick bite to eat before the Adele concert at the Verizon Center.  Daikaya (known for its ramen) was a 40 minute wait.  But then we happened upon this hole-in-the-wall that advertised fresh hand-cut noodles (called 手拉麵 in Chinese).
The noodles can be either put in soup or stir-fried, and you can choose your toppings (vegetarian, chicken, roast pork or roast duck are some of the choices).  I opted for soup with roast pork on top.  Jim went with the little soup dumplings（小龍包) and normal dumplings.  They were good but not memorable.
On the other hand, the noodles were excellent—thick and substantial, the way hand-cut noodles should be.  The broth was simple but filling, and the roast pork was excellent—flavorful and meaty.

We believe the quality of the dishes here is completely dependent on what you order.  Based on our limited data points, I would lean towards ordering Cantonese specialties such as roast pork as well as the hand-cut noodles (which aren’t a Cantonese specialty but are lovely anyway).
We will definitely be back to try some additional dishes.  If you’re looking for a quick and inexpensive meal around the Verizon Center, Chinatown Express should be on your list!
