Washington DC on the Whole 30 in Travel and Dining Out Posted September 27, 2017 I ate at the Silver Diner in Clarendon when I was there in Jan. I had a flat iron steak with a salad and potatoes. I had to ask them to make a few changes (I think it was just butter that wasn't compliant). I just looked at their menu online and that's not on it any more. It was GOOD. They probably would accommodate as well still.
