Review of Old Ebbitt Grill

Explained I have a gluten allergy. Staff was very nice but not knowledgable. Ordered a salad with no dressing and olive oil on the side. Salad came with premade salad dressing. After assuring me it was made with a white vinegar that would not cause a reaction, I ate it. It was delicious. But twenty minutes into the meal I got a reaction. Should have followed my intuition and sent it back.
