We stopped by for lunch on a weekend, and were very pleasantly surprised! The cuisine is super-tasty and fresh, and the staff were very pleasant and attentive. The baboy appetizer had light and crispy tofu. If you're there for lunch try the "log" with sweet sausage - it is like a breakfast with the side of fried egg and garlic rice, and was wonderful. The plantain "bun" sliders are amazing! (Instead of a bun they use plantain pancake - clever and yummy.). The appetizers are $6-7, and most entrees are around $10, plus/minus a few dollars.
It is less than 1/2 mile from the Amtrak AutoTrain station, on the other side of i-95. If you're looking for great, unique food at a reasonable price and not have to worry about driving all over Lorton to find a bite to eat before getting on the train, this is the place to go.
