Hunan Shrimp Boat is great! Nothing in the city can compare to the way it cleans you out! Not even 5 minutes after eating it, I was running for the toilet. If your pipes are backed up, go to Hunan Shrimp Boat!
So far this is as close to NYC as I've found in DC. The dumplings are good (especially steamed Taiwan style) and the noodles are fresh. It's downstairs, no frills and cheap -- just right!
Good customer service and you watch them cook your food. The food taste great but I gave them 4 stars because there are a lot of people loitering out side.
