The menu marked which items were not gluten free.
They bring out drinks with a paper straw in the cup, so tell the waitress at your drink order that you want no straw.
I told the waitress I had a “gluten allergy”, since that is what people can relate to. She looked nonplussed by that. I ordered the maryland crab soup and caprese salad with crab. It tasted great, was generous with the crab and I have not shown symptoms of glutening. 4 stars because the drink came out with the paper straw in the drink.
