I will be visiting DC with a friend in the next couple of weeks and will be staying downtown (PA Ave. Marriott, I think). We would like to have one really fine dinner out but don't want to do a lot of driving. Any suggestions from those of you who are familiar with the area? I was thinking something on the order of Chez Panisse. We both love Asian, Italian, seafood and Californian and don't mind spending $60 - $70 for a good meal.
