Before the trip, I did my usual research for gluten-friendly establishments. I did some research online, but also found some great recommendations in The Essential Gluten-Free Restaurant Guide from Triumph Dining. We ended up having some wonderful meals while we were there. We had dinner at The Capital Grille to celebrate the BIG birthday! We also had dinner at Clyde's of Georgetown and Legal Sea Foods (one of my favorites in many cities). We also had a great lunch at Mitsitam Cafe located inside the National Museum of the American Indian. It is set up cafeteria style with different food stations. Gluten-free options are actually labeled at each station and the staff is very helpful. You don't want to miss this one!
I had a few other recommended restaurants that I wanted to go to, but we were only there for a few days. I'll have to add them to the list for my next visit!
