Fu Lai is convenient for the Oak Hill crowd. It's located on the Oak Hill shopping center right before you hit the "Y."
Their menu includes the regular chinese fare, but they also have excellent choices for those who want a different approach. I highly recommend their beef basil. Their beef is consistently stir-fried to tenderness and their vegetables are never soggy. If you can handle the amount of food, try the crab rangoon. These actually have crab meat!
