As others have said, Grapeseed is a great choice for foodies. Not inexpensive but good value for what you get. To cut costs, here's some advice: The beef-tip appetizer is a good-size portion. Go during Restaurant Week (both DC and Bethesda RW are twice/year), look for Groupons, and try their lunch deals, either 12.00 or 18.00 for appetizer and entree.
