I'll be in DC next week for some business training and a nice visit with my sister. I'd like to be able to take her out for a couple meals during the visit. Working on the Hill, she dines out frequently, so the challenge is to find a couple suggestions that she might not have visited and will wow her.
Perhaps a nice dinner at fancier restaurant that she might not yet have tried, perhaps a wonderful hole in the wall she never dared to enter before. Which restaurants might you suggest, and why? If reservations are needed, will a call 9-10 days in advance be too late?
