I'll be in DC later this week with my 10-year old daughter. She and I are both adventurous eaters, so the food doesn't have to be kid-friendly. We are looking for a couple of lunch recommendations. We'll be staying at the Capital Hilton (checking in at lunch time) and spending some time at the museums on the mall, so any recs in these two areas would be great. We won't mind hopping on the metro for something that comes highly recommended, either.
Thanks in advance.
