Can't believe I've never been to D.C. before, but it's never too late. We will be there for four dinners and five lunches the second week of March. One night is a "special" chef's dinner at David Greggory. Have narrowed down (with much difficulty) to Jaleo, 1789, Johnny's Half Shell and Tosca. What are your thoughts on my picks? We really don't want to have to dress up too much, so are any of these automatically eliminated? We prefer casual places with really great food. What about some Asian recommendations for either dim sum or just good for lunch. We'll be doing the usual sightseeing stuff, so any places that work out location-wise, would be great. Thanks in advance and I can't wait to visit your amazing city!!!
