We enjoy the Happy Hour religiously! The sushi and all small plates are 1/2 price. We get the spicy firecracker shrimp roll, lamb pops with a tangy goat cheese sauce, crab cakes, and the beef short ribs. All are DELECTABLE and a bargain between 3pm -6pm. The decor is gorgeous and right out of the orient. The staff is wonderful and attentive. The service was great. The only thing that we didn't like was the music at Happy Hour. It's a techno type sound that you get in a club. The music changes during dinner though. If you get to the National Harbor, you MUST visit Graces.
