Any suggestions for not-to-be-missed dining experiences in DC?
We are from Dallas and are staying at the Westin Washington at 1400 M Street NW for 5 days. We will not have a car, but will be depending on the Metro for getting around. Since we are traveling with our two children (ages 13 & 9) we will be somewhat limited to our dining choices, but since we are also accompanied by their grandmothers, we might be able to convince them to babysit one night while we enjoy a more romantic/adult dining experience! Since we will be out all day doing the usual tourist things (museums, monuments, etc.) we are open to breakfast, lunch, and dinner recommentations, but would prefer dinner either close to the hotel or easily accessible by Metro.
Probably need more kid-friendly recommendations, though our children are well behaved in the more adult restaurants. We enjoy all types of cuisine, but are definitely looking for more "local" flavor and atmosphere.
All suggestions are welcome and appreciated.
