Just went to A&J Restaurant about a week ago. One of the best dim sum restaurants in the area. I have been to several chinese restaurants throughout Bethesda and the Washington area and this is by far the best place. A bit of a hole in the wall, this restaurant is authentic with dirt cheap prices. To stuff my family of four cost $44! The food was fantastic especially the Shaghai style soups and the bean curd. Most would pass by but this is the place for real chinese food.
